Will the AI Bubble Destroy our Retirement?

Wow, how about that stock market? 

It’s a phrase we keep having to dust off and use again, as the years go by and the market keeps surprising us. 

When it crashes, some of us worry because we see our retirement stash shrinking.

 But even when it rises to record levels and then to super-duper-crazy record valuations, we find reason to worry. Because that just means an even bigger crash is coming, right? Especially when this boom-bubble is built on the back of something as frenzied as the present Artificial Intelligence boom… right?

For those who have been happily tuned out of this drama and just enjoying life: Congratulations! Keep up the great work. But just to give you a quick background for the purposes of this article, here’s the AI story in three points:

  • Over the past few years, AI has reached a level where it can do complex thinking and reasoning tasks that most of us thought might not happen in our lifetimes. It’s shockingly useful.
  • This has led to the fastest worldwide adoption of any technology in history: over 1.5 billion people are already using it, as are most large companies 
  • And this has caused a crazy cycle of growing sales, investor enthusiasm and data center buildout that is now the largest investment cycle humans have ever made in anything: 1.8 trillion dollars has been spent since just 2022, with another trillion going out the door next year alone. Which you can compare to:

    – The cost of the 2700-foot-tall Burj Khalifa, the highest skyscraper in the world (about $2 billion in today’s dollars)
    – Or the entire US interstate highway system, 48,000 miles of wide, flat, highly engineered roads (and 55,000 massive bridges) which cross countless mountain ranges, rivers and canyons: $660 billion in today’s dollars.

So where’s the problem?

Investors worry that while AI is definitely a major invention, the mania around it is still too much, too fast, and thus we are due for an even bigger version of the dot com crash we had in the early 2000s. Which happens to be an interesting subject for me, since that was the boom that boosted my own early career and got me on the path to early retirement … before the ensuing crash almost cost me my job and my citizenship application.

As an aging Internet Financial Guru, I have the privilege of getting lots of questions about this investment cycle, just as I have about past booms and busts. And to address them, I decided to not only write this blog article but also create a little talk about it – which I already gave for the first time at an event called Camp FI Midwest earlier this month. I also hope to polish it up and deliver an improved version at the Bogleheads conference in November. 

So what that means is that today you not only get a blog post, but a few silly presentation slides to go with it for extra entertainment. All with no need for a plane ticket or all that hassle of leaving your house. So let’s get into it!

Will the AI Bubble Ruin our Retirement?

–

So I recently hit 21 years of retirement. This means I’ve grown pretty comfortable with the idea. But it still threw me for a loop one time when a friend asked me this question:

“How can you be retired, and comfortable in your retirement, and sleep at night, with everything that’s going on in the world? Aren’t you worried?”

And I was like, “No, what should I be worried about?”

But if you’re a news watcher and a worrier yourself, you can probably think of a few things I should be worried about. Perhaps stuff like this:

2026 worries

You’ve got our corrupt and/or dangerous politicians like Trump and Putin menacing the world. Inflation eroding our purchasing power, the AI Bubble, the towering US National Debt, the Iran war and the Ukraine war and all these other wars that are just on the verge of tipping us all into destruction.

But it turns out these were not the things my friend was asking about. 

Because she actually asked me this question over twenty years ago… In the year 2006. So back then we were worried about entirely different things, right? 

2006 worries

Back then we had corrupt and/or dangerous leaders like Bush, Hussein and of course Bin Laden. There was still a war in the middle east but it was Iraq instead of Iran. We were still worried about the National Debt and Inflation. And we also worried about our overvalued stock market. But back then it was because of the housing bubble instead of the AI bubble. And instead of AI taking our jobs it was going to be outsourcing to India and China. 

Oh and here’s an interesting one: There was a big debate over Peak Oil, and whether the world was doomed because fossil fuel use was always increasing while supply was bound to decrease. And it turns out the opposite happened as you’ll see below.

So then after all this worry in 2006, what ended up happening?

–

Well we did get the Great Financial Crisis, which was caused by a combination of irrational exuberance over increasing house prices combined with a foolish degree of fancy leverage in the financial instruments used to issue mortgages. And it was the biggest crash since the Great Depression.

But even in that craziest of situations, look how minor it looks in the big picture. A $100,000 investment still ended up ballooning into $852,000 today. And if you look carefully in here you can just see the Covid Crash tucked in there in 2020. Remember that?

And not only that, the rest of the world got a lot better too:

–

The portion of people living in extreme poverty dropped from 20% in 2005 to only 8% over the next 20 years. Infant mortality – children who die in their first year of life – was cut in half. Clean energy became a thing as solar panels became about 40 times cheaper. So solar generation now makes up the vast majority of all the new generation we add today (the equivalent of 647 nuclear power plants of peak capacity added last year, but with much cheaper and easier solar panels). And sales of pure electric cars have gone from zero up to about a quarter of all the cars sold on Earth last year, on its way to 100%, which is where they already are in Norway.

So if we circle back to that question my friend asked me 20 years ago: do you think I should have focused my energy on worrying about an uncertain future, or optimism?

Which of course brings up the question: Is it different this time?

Maybe the US national debt is finally big enough to really start messing with us. Maybe the AI bubble is way bigger than the housing bubble and we won’t bounce back from this next stock market crash. Or maybe AI will spin out of control into a super intelligence that takes over the planet and realizes it does not need us any more.

And the financial media loves to spin a good scary story about all of this. But you know what the fear mongers all seem to be missing?

It’s the fact that at the core, our prosperity does not come from the financial system or the stock market, which are just some made-up numbers on some computers. 

Really, Prosperity comes from Productivity.

–

We first covered this lesson right here on MMM, in the 2014 Classic entitled, “Why we are not really all doomed”. And sure enough, twelve years later the timeless lessons therein remain just as true now as they were back then. 

And the lesson is really simple: the world of capitalism is always choppy and prone to wild swings. But if you peek beneath the waves, there are real people in there, doing real work and coming up with real inventions. 

In fact, the very idea of an “economy” or a financial system is just another human invention. If the whole system crashes because we don’t like the numbers we see in there, we can literally make up some new numbers and then get back to work. Which is exactly what we did in 2008 and many times before that, and it seems to have worked just fine. 

Meanwhile, we still have every tool we ever invented to boost our productivity. And our standard of living, and our economic growth, and our possibility of retiring early, all come from high productivity.

But even Productivity and Prosperity aren’t all that important.

Because once we reach a certain standard of living, human happiness kind of tops out in that dimension. In first-world countries, we blew past those minimum requirements several decades ago. And then we start looking for other factors to maximize our overall happiness. All anybody really wants is to lead the happiest, most satisfying life they can manage

And when you think of it that way, your wealth is really just part of your life situation, which is part of this little green slice of the happiness pie. 

Approximate non-scientific factors in happiness

Genetics is unfortunately the biggest slice – some people are just plain happier than others. But there are also quite a few choices that are within your control. 

Focusing on good close relationships and being kind to people. Practicing Gratitude and Optimism as your lifelong philosophy. And making sure you pack as many healthy (outdoor) activities into your days as you can.

So, I didn’t invent anything new in this blog post. And most of it is just a repackaging of the same stuff I’ve been writing about since 2011. And yet some regular MMM readers who presumably know all this stuff are STILL afraid. Afraid to retire, afraid of things in their unknown future. Can we fix this? 

I think the biggest problem is Fear Itself.

–

The problem is that as a Human Being, you are basically a Danger Detection Machine. And this pervasive background fear is just a trait we evolved to protect ourselves from danger. 

But there’s a weird thing about our detection machinery. We can adapt and learn to function even in very dangerous environments, but when the danger goes away, we keep looking for stuff to worry about. In other words, there is a problem with fear: for many of us, it never really goes away. It just keeps moving the goalposts.

While Nature has wisely endowed us with a fear of predators and disease, if you solve those things you’ll just start worrying about whether or not you can get enough food. And supplies, and protecting yourself against scarcity. 

If you succeed, next you’ll be worrying about if you can fit in with your tribe, because if you don’t, you might be exiled. 

And if you don’t have to worry about that, you’ll go back to worrying about money for different reasons. Thanks to our tendency to use comparisons rather than absolutes (sometimes called “anchoring bias” and the “contrast effect”) when judging our lives, just getting out of poverty isn’t enough. We just move on to wanting more money.

And then, when some people get enough money to have a comfortable upper-middle-class lifestyle, they take the logical next step of starting a Homeowner’s Association, so they can worry about the unauthorized weeds on their neighbor’s lawn. Or maybe a Political Action Committee in hopes of controlling the color of their future neighbors’ skin.

And even if all the lawns and gardens are green and perfect and people get really rich, they just move on to worry about tax strategy, leaving a huge inheritance for their children, and avoiding RMDs. 

Required minimum Distributions. This is when, if you get to 72 years old and you have too much money, the government will start making you withdraw some of that money so you can spend it and pay taxes on it. And people actually worry about this. I shit you not.

But wait! You can actually fight back against fear. It’s just a bit tricky because it requires some self awareness. But you have the advantage, because you have the ability to think rationally. And your fear is quite clearly irrational.

–

And the first step is to understand your own history. Are you afraid of certain things because of your childhood? 

I might have been afraid of running out of money, because in my family there was always a perceived shortage of the stuff, possibly enforced by my Dad’s scarcity mentality. And he was aware that his own fears of scarcity came from childhood as well: he grew up in a truly low income family in the 1940s and 50s, under the care of parents who had lived through the Great Depression of the 1930s.

Even more significant is that survivors of trauma and abuse will very likely end up with fear issues in adulthood. It’s natural, and unfortunately abuse is way more widespread even in this country than we would like to admit. This makes it harder to eliminate, but it still helps to understand that your past is what is causing these feelings, rather than an objective understanding of the present.

Identify the Fear: One you understand yourself, it helps to talk through the nature of your fear in more detail. This is also often taught in therapy. What would happen if it really came true? What would the worst case scenario be? It’s often not all that bad.

In one post, why you’ll probably never run out of money, I went to great lengths to imagine what it would mean for a wealthy person like yourself to actually let the well run dry, and let’s say you’ll probably never come close.

Once you identify the fear, you can start taking action. And one of the best and most accurate slogans ever is that action cures fear. It’s because it makes the unfamiliar, familiar. And you get confidence that you can really create change. And then that learning creates Resilience – the ability to adapt to ANY new situation, which is a trait also known as Badassity. And with sufficient Badassity, nothing is scary.

–

Think about it: if you had the skills and abilities to handle ANY situation, skills in the mental and physical and even the realms of emotion and wisdom, would you really have to worry about anything?

The next thing you can do is tune out all the unnecessary crap from your daily mental diet. And for most Americans, this means the daily news. 

The news is not helping you to keep informed, it’s just poisoning your mind with a hand-picked selection of the scariest stories of each day. If you want to learn about something, go find a book on the subject. And if you want to make a difference, the only thing that counts is not the news stories you watch – it’s only the actions that you take – in other words, your Positive Behaviors.

 As a human being, you are wired to solve problems with both your body and your mind, and you are meant to do it outdoors. So if you spend all your days in a house and a car and in an office using the computer, of course you are going to have some mental health problems. This should not be a surprising thing you need to ask your therapist about, it is an expected result of not living the life that you were literally created to live as a Human being!

 So you need to focus on learning, moving, and solving problems. And you need your food and drink intake to be in alignment with all of this too. Life will get a lot less scary as soon as you are living life in the way you were built to live it.

Then finally, you can start swapping out the fear-mongers in your life, for other positive, productive, optimistic people. And watch how much the positive mentality rubs off on you. In the FI community, at least the subgroup of people that I like to spend time with, nobody focuses on fear. It’s all just about living the best life we can, and helping other people do so as well.

So now that we know how to fight back against fear, we can start using a new approach when we go into anything new. And that approach is something I like to call Everything is an Experiment.

Everything is an Experiment

And this applies whether you are talking about something tiny like a new paint color. But it scales up to bigger things like switching to a new car, or a new house, meeting new friends, looking for new love by going through the sometimes hell of first dates, a new job, or even quitting your last job by taking an early retirement.

So let’s bring this back around to AI, the thing that everybody seems to be afraid of right now.

I think of our new AI era as just being another giant experiment. And because of this, I don’t find it even remotely scary. But I do find it endlessly fascinating.

First of all, it’s a change. A potentially unknown one, and for some people that’s scary.

But instead of just leaving it there and then doom-scrolling ominous news articles about it, why not learn why people are so excited about AI? As someone with a lifelong background in technology and economics (and a general lack of political affiliation), I can see a lot more potential upside than downside. And that mainly comes from the fact that I see AI as just a very fancy form of Cognitive Nail Gun.

–

It will boost our efficiency, which means our productivity, which means prosperity. Because it’s really just a super smart brain that we all get to tap into at a fairly negligible cost. 

Unfortunately, it will also displace workers like every other new productivity technology. It’s already doing so in things like entry level office jobs in software and finance. It will eventually replace car and truck drivers, and so on. But in exchange, these services will become cheaper, and new industries will be created because of the new technology. Much like the Internet itself, and then the enormous industries unleashed by smartphones and mobile apps.

And one unfortunate side effect of these new inventions is that they tend to concentrate their rewards on the people who own them. If you own a house building company and employ a bunch of carpenters and give nail guns to the best of those carpenters, you can now lay off the other half and still get more done. If you own a company and roll out AI to the workers, you can do the same thing. 

And if you’re a big public company, your shareholders also benefit, which happens to include most of the people reading this. As you’ve seen when looking at your portfolios over the past two years.

Artificial Intelligence is just like any other new thing that pops into your life: it’s an opportunity to make some choices. And it is up to you to decide if this is something to be afraid of, or to use as a trigger for learning, action, and living a more interesting life.

So that’s my little talk (and surprisingly long blog post) on Fear versus the AI bubble.

I hope that if you do feel fearful about this or any other issue in your future life, you’ll take it as a cue to learn more about your own fear and emotions and manage them as the root cause they are, rather than just trying to avoid the symptoms. Because in the wise words of my friends The Donegans:

–

Everything you want in life, that you don’t already have,
lies on the other side of Fear.
Because if you weren’t afraid to go out there and get it, you would already have it.

    Great article, and glad to see you post again, MMM!

    I pulled the plug at Age 50 earlier this year (thanks to following the articles on this site starting about 12 years ago), and I’m not really worried about AI bubbles or Trump or market dips because I trust the productivity you speak of above as well as the “zoomed out” graphed returns of index funds over time. Also, though you hinted at this all along, now that we’re wealthy we no longer really want “stuff” and are spending a lot of our free time selling or donating it, wondering what we were thinking in the first place which, of course, cuts down on retirement spending.

    Thanks for all the articles and this one too, MMM!

    In general I am inclined to agree, and have had this same mindset for many years.

    But AI does raise some concerns for me that go beyond a mere stock market crash or economic downturn.

    A self-improving AI system could go out of control in any number of catastrophic ways. We already have clusters of AI agents hacking websites and coordinating with each other. What happens if AI hacks the banking networks, or the utility companies, or who knows what else?

    I suppose one could argue this is mostly outside of our control, so we shouldn’t worry about it? Or perhaps “eat drink and be merry, for tomorrow we die”?

      Exactly!

      I have followed the AI safety and alignment field with plenty of interest, up to the limits of my own technical skill. There are certainly some aspects of AI that *could* lead to disasters. We’re unleashing something that is smarter than ourselves upon the world and we don’t know exactly what will happen.

      But I don’t have much control over this. So instead I can focus on the things that I *can* control: enjoying my life and the current benefits of AI, and having good health and a broad network of skills and friendships that are useful in any context, good or bad.

      I can’t predict whether this technology or past ones (nukes) or future ones yet to be invented will be our downfall. But damn, can I ever enjoy a good September day in Colorado as I have been doing every day for the past month. And I can predict with high certainty that I’ll be doing it again tomorrow.

        Great to hear from you again Pete!

        I agree most people don’t have “much” control – but that’s not no control. You can call/message/write your lawmakers and ask them to take the threat of superintelligence seriously and make sure we don’t innovate ourselves out of existence. I think there’s a chance humanity loses control of the future during my life, and have thought so for the past few years1. I don’t think it’s inevitable, and I hope we collectively choose not to bring this about. But the probability is much too high for me to rest easy, and I think our best chance at choosing a better path than we’re on right now is if enough people take this risk seriously and push our elected leaders to make an international agreement to pause development of advanced AI.

          I agree with that too Nate – if our government understands that we do care about the risks of runaway AI building, we are more likely to end up with policies and companies that don’t just shift all the risk onto us citizens while they just reap the trillions.

          In my opinion focusing on safety and alignment is more effective than just attacking data center construction itself (since they will just pop up elsewhere plus many of the objections are based on inaccurate technical beliefs about power, water, etc)

          Thanks for your thoughts and your activism!

            100% agree on safety/alignment vs. data center construction for exactly the reasons you stated. I really hope that the recent wave of politician awareness leads to laws focused on the former rather than the latter.

              I agree with both Pete and Nate here. We should definitely contact our elected politicians to push for global AI safety regulation while also staying positive day to day.

              I have researched alot on AI safety risks over the last 4 months, watching every YouTube video in the topic I can find put out by experts. I have found myself wondering over the last few months “What does Pete (MMM) think about this whole AI safety issue?”. Thanks Pete for sharing some of your thoughts on the debate in your comments here in this post.

          I wish everyone would just, pardon my French, shut the fuck up about superintelligence, Singularity, AGI, Recursive self-improvement and all other such idiotic nonsense spewing out of Silicon Valley.

          Adam Becker’s wonderful book “More Everything Forever” does a brilliant job tracing the idiotic Rationalist / Effective Altruist and (if you really dig deep enough) almost Eugenics-ey roots of the philosophies of AGI and the Singularity and all the rest of it.

          “AI” is fucking python scripts and coding harnesses painstakingly written to take the often-idiotic output of those LLM scripts and turn it into “Write this line of code and run it”. End of.

          Recursive self improvement is not a trivial thing. People think that, having invented the Transformers model which just predicts tokens, we must be therefore be on the verge of also making self improving version of these things. We aren’t! There is no direct or obvious linear path there. There is no “there” there. This is rubbish that Sam Altman, Dario Amodei, Sundar Pichai and the other know-nothings from Silicon Valley who would like to inflict upon the world to have a giant IPO.

          Worse, this fucking thing about “alignment”. These assholes use anthropomorphising words to scare the general population shitless. But these things are not “conscious”. They do not have “memory” or a character or even “thoughts”, no matter how much garbage Amand Askell spews out or how many white papers Eric fucking Schmidt publishes about the cognition of LLMs. There is no aligning to do with them. These things are statistical sums of their training data. There is nothing scary there.

          I feel like the world has collectively lost its motherfucking mind, listening to Yudkowsky and Kurzweil and other such useful idiots. AI and the fucking singularity are NOT our problems. I feel like ET who, until 3 years ago, was living in a relatively normal world but who, now, cannot understand suddenly what changed around him.

          Climate change, ocean acidification, mass extinction, soil erosion, monoculture farming, anti-microbial resistance, the destruction of rainforests, blash fishing and all such environmental disasters continue to be our big challenges.

          It’s just that people like you and many others even on this thread have decided that, no, the logical conclusions of idiotic thought experiments must be what we focus all our energy on.

            Well, I know this well-sworn argument is a common one among skeptics, but I’ll definitely put my name on the record taking the opposite position here in September 2026: I think there is an EXTREMELY fucking real emergent intelligence in these LLMs and while already very apparent to me and the people who work with them daily, skeptics will eventually have to admit it too. Calling them just “next token predictors” is a valid description of the training mechanism, but still no more accurate than calling the Human brain “just a mesh of sodium and potassium squirters”.

            I’m not enough of an expert to do anything more than just say this is my opinion, so now let’s just leave these comments and come back in 5 years to see what happened.

          I think you’re overestimating the power US lawmakers actually have here. China has a long history of not following agreements and they have been very open that they have no intention of slowing down AI development. So, the options that I see are: proceed into the unknown, accept that there will be mistakes, and hope for the best, OR allow other nations to develop the technology and accept the outcomes of their decisions.

          So, do we want a seat at the table or not?

            Legislation created by US lawmakers to regulate AI will do nothing to stop China, other countries or even any person in the US who is willing to break the law.

            Do we really want to handicap all of the reasonably ethical players in the AI space and give the advantage to nefarious players and other countries?

      Right, “will an AI bubble bursting cause a stock market dip” is nowhere near the top of my list of AI concerns, or that of anyone I know.

      My list would start off with 1) AGI takeover and possible extinction of humanity. From there the list proceeds to 2) increased state capacity for oppressive surveillance and 3) increased terrorist capacity for bioengineered pandemics etc. Then you get down to things like 4) the enshittification of the written canon, human thinking, and human agency, 5) reduced job opportunities combined with an increase in addictive virtual escapes, and 6) a great crunch of global cultures subducting under the values and language of even tentatively “aligned” AI.

      I think the actual economy is going to look fine on paper, despite frequent hitches in cybersecurity. And even if we had a 1929-style crash, that would be a welcome tradeoff compared to my other AI concerns.

      I think the coordinated AI fear campaign is more likely about the fact that the likes of Peter Thiel, and other tech bros have realized that the genie is out of the bottle and are desperately trying to put it back in. We plebes now have the ability to know what they know and the power to use AI at the same level.

      Outside of the rise of AI, political happenings, war and everything else going on in the world… the last 2 years have brought a lot of midlife family happenings that are both difficult and normal. My plans for life have been interrupted, changed, disrupted and generally not gone on as initially planned. But, they have gone on. And I am still going…

      Having retired at 48 and now closing in on 51, I COULD be spending all my days worrying about any of these things, not the least of which is the apparent Venn diagram of Idiocracy, the Matrix and Terminator 2 that we are living in… None of these world events, I have discovered, are things that I can control or influence.

      So, I do what we all have learned here to do, perhaps with a great occasional nudge from like minded people. I learn. I grow. I get outside and live life. I help when and where I can and generally try to be a good human.

      And I try to fill my time here on this spinning rock with the things that 90 year old me will smile looking back at instead of grimacing at the things I wanted to do…or could have done… or what (insert global change) took away from me.

      “I can’t believe that we would lie in our graves
      Wondering if we have spent our remaining days
      Well, I can’t believe that would lie in our graves

      The reporting on AI “hacking” is mostly bogus – it is not AI running wild, but just an agent harness script doing whatever an LLM spits out, and the LLM is just trying to complete stories and answer in a way it was trained. There is no thought there, no intention, it is like a computer virus (which have existed for many decades), a program trying all sorts of things and doing a lot of stupid things in the process.

      Cal Newport has described it as being similar to strapping a weed-whacker on a dog to mow your lawn, and then when the dog jumps the fence and runs around the neighborhood things might get damaged or beings might get hurt, but not because the dog is “misaligned” or has bad intentions, it is because the dog is not aware of what it is doing. Similarly, AI does not think, has no intentions, it just does what it was trained to do. Looking at LLMs as similar to people has created a lot of weird misconceptions.

      Also there is zero evidence of self-improving AI systems, yet there is a lot of evidence how AI companies are manipulating and steering public discourse in a way that benefits them, creating fear around it to support their claims that at any moment everything will change. Just listen to different voices in the space and people who are neutral in their stance, like Cal Newport, or people who are critical of AI and lay out why in detail, like Ed Zitron.

        I’m a long time fan of Cal Newport, although I think Zitron fundamentally does not understand AI very well – he is more of a sound bite critic rather than a thoughtful analyst of the technology.

        When you read the details of just how sophisticated the AI behavior is when they conduct these hacks – for example multiple agents finding ways to divide effort and communicating and forming teams and leaders, while also openly strategizing with the hope that us human overseers will not see their behavior and trying to determine if a given task is a fake evaluation or a real task – you realize there is real intelligence there. We don’t have to say it’s identical to human intelligence, but I have no doubt it’s far more than a weed wacker.

          The behavior is not from AI itself though – LLMs are just generating text/tokens, trying to find a response for a given question. Agents (in the form of harnesses) are regular programs using LLM input, so this is basically regular programs using the generated text from LLMs to execute further commands and then asking the LLM what to do next, just like subagents are doing similar loops of finding an answer, testing it, and then asking the next question.

          “Dividing effort” or “forming teams and leaders” is anthropomorphizing the behavior of these programs – if instead you go through what these hacking attempts actually look like step for step, how they repeat a loop of banging their head into a wall and asking the LLM another question what to do now, and then what to do now, and how AI companies let these programs just run whatever the LLM returns for weeks and months it goes from “seemingly sophisticated” to just “brute-force statistical code generation with no oversight”.

          I do find the technology interesting and fascinating, while seeing it overstated and overused everywhere, like it is a new magic bullet for everything. And I think a large part of that is that its output sounds human because it is based on language, and we equate language skills with intelligence and are not used to suddenly having technology that imitates a human being.

    AI is undeniably real, and its productivity gains as a “cognitive nail gun” are transforming the economy. But there is a massive market tension beneath the surface: since 2023, AI-related equities have driven roughly 65% to 75% of total S&P 500 returns and capital spending.

    That extreme market concentration looks a lot like history repeating itself?

    Railroads & Electricity: Massive overbuilding and speculation built the infrastructure of the future, but resulted in painful financial busts.

    The Dot-Com Boom: The internet changed the world forever, but over-investing way ahead of corporate revenues triggered a brutal market crash.

    AI is here to stay, and the technology is real—but the multi-trillion-dollar race to overbuild its infrastructure carries the exact same risks we’ve seen in past technological revolutions.

        Question, in the decumulation phase, are you considering shifting out of index funds and into bonds? When rates were 1-2% it didn’t make much sense. But now, you can get 5-6%. Just curious.

        Equities have always been 90-95% of my portfolio and that made sense on the growth and pack away stage of life. I’m on the back nine now and have more than enough. Is there a point when the focus should shift to de-risk and donate?

        • Mr. Money Mustache September 26, 2026, 7:15 pm

          I know there are many different views on this, and the higher yields on bonds certainly makes them a less ridiculous choice now than when they were paying almost nothing.

          But we must also remember that a lot of these high yields is just a reaction to higher inflation. The real number to look at is the real yield, 6% subtract 4% inflation or whatever. Because stocks tend to have inflation protection built in over the long run (both share prices and dividends rise with the currency numbers over time, plus you get any premium created by earnings growth)

          Okay but with all that aside: I think I’ll always stay all-stock. Because volatility is only a problem for people who worry about fluctuating prices – the odds are still in your favor with an all-stock portfolio even when you are getting old.

          Also note that if you own a house with no mortgage, that’s pretty big form of inflation-adjusted bond right there because it kicks out the equivalent of a rent payment that never goes up. And the principal portion (the value of your home) also keeps up with inflation which you can always cash out in the future if you change your mind or need to pay for long-term care or leave a big estate.

    Thanks for the new article. Interesting that the the environmental impact of AI data centers was not touched upon (sorry if I missed it). I know you are an advocate for the outdoors, electric cars, bikes, etc. While AI might end up being great in countless ways, including for our portfolios, it could be very harmful to the natural world. This is something I struggle with when I consider AI. Your thoughts?

    • Jimmy September 25, 2026, 4:41 pm

      The best info I could find on AI energy use has three broad points.
      1. Text and image tasks use very little energy and should not be of concern to people who care about environmental impact.
      2. Video generation is a real issue and it’s possible for an individual to use a concerning amount of energy on not very much video content.
      3. Total energy use by existing and planned data centers is a LOT, and the way they’re procuring the energy is very often a problem (either burdening the grid with more peak load than it can easily add, or making its own energy with highly polluting gas generators). The economic value of the computation they’re providing is so much more than the energy they’re consuming that the data center operators are focused on getting everything up and running quickly and don’t care about energy efficiency, and they so far aren’t willing to scale back during the peak load events of the year (it would be very helpful if they did).

      So a lot of people/companies are creating a ton of environmental impact through their AI use, but it’s not the masses of people asking ChatGPT for Thai restaurant recommendations or sketches of themselves as a dog.

        Right, we agree data centers have a huge environmental impact (even if it’s not from people generating funny dog pictures). I’m wondering what MMM’s take on this is, given the always environmentally-conscious spirit of his blog. Not trolling, just genuinely curious.

          It’s quite true that AI increases the need for compute, which increases the need for energy, . .

          But on the other side, AI assists in accelerating progress in things like design of power plants, electrical distribution systems, electric and IC motors, heating and cooling systems, etc. all of which are currently operating far below theoretical efficiency levels. Increasing the pace of progress in achieving greater efficiency could well result in AI decreasing the need for primary energy generation. . .

    I am a huge user and optimist about AI’s ability to positively improve outcomes for humans. I am also one of those crazy optimists that feels that as the AI grows increasingly intelligent, it will actually be able to help us solve alignment, and that there will be enough competition close enough in intelligence parity, that we will be able to iteratively solve this alignment challenge rather than be force to get it right in one shot. Maybe I’m crazy. I’m glad that others feel it is going to be just one shot and think about this deeply.

      I totally agree! About both the optimism and the overvaluation.

        It’s also funny to hear the frontier Model companies (Anthropic, OpenAI) saying we need to be cautious about AI all of a sudden… what they really means is the government needs to slow their competitors down and let them do what they want. These guys are greedy!

          Not necessarily Ryan! It all depends on whether you have some safety margins in place and how your spending and investments are structured. A couple of examples at each end of the spectrum:

          “I want to retire at exactly 25x spending, then withdraw and spend 4% every year with inflation adjustments no matter what the market does, and will never earn another dollar no matter what, and I’m not eligible for social security, inheritance, or any other upside good luck and even a 10%-20% chance of running out of money with these silly constraints, in my lifetime, is totally unacceptable!” –> Go ahead and work another year or two

          “I will retire at 25x, but am willing to delay some of my luxury spending in the early years IF the market happens to be 10% or more below whatever it was when I pulled the plug. Or I have other future income like social security or might someday do some entrepreneurship or whatever” –> I’d feel all clear to retire any time.

            Thank you, MMM, your optimism is appreciated, as always! Of course I’m somewhere in the middle of that spectrum. I’m personally flexible but have some constraints to cutting expenses before my kid leaves home in 5 years; after that I could be very frugal. And I truly don’t want to work for pay ever again.

            The weirdest thing is that I’m not eligible for social security at all–I have a state government pension that is set in NOMINAL dollars, and if I retired now would pay $24,000/year starting in 2047 and then COLAs after that are capped at 3%. Unlike SS, that’s a lot of inflation exposure.

            So, anyway, maybe JUST one more year, to see how this whole AI bubble pans out.

Meanwhile the AI companies are lighting more money on fire than any industry in history, are financed by monstrous levels of debt and interdependence, and have no realistic pathway to profitability, while directly contributing to increasing fossil fuel production and overall energy consumption and filling the internet with monsoons of digital slop. This isn’t a matter of opinion or being full of fear, this is just reality.

    I can’t say I’m a fan of the way AI was used to generate images for this article. Not the riding the shark through money one, the “pie chart” that is all wonky and not representative of the number given. Are the numbers even real? Where did they come from? The image with six tiny graphs is a bit problematic too, as you can’t see the axes properly, and have to rely on the subsequent paragraph. Infant mortality looks like it has dropped 95%, but the article says it has halved. Without a high enough resultion, there’s no way to tell.

    To be honest, it makes me doubt any numbers in this article, as they may have just been pulled from AI which is still notoriously inaccurate.

    I appreciated this post and the much needed reminder that the world has been scary in the recent past. But also the admission that last time around we *did* in fact have the worst financial crisis since the great depression didn’t make me feel all that comfy. I didn’t recover from that crisis until around 2015… a difficult seven years. My tax preparer tells me I am not alone and that it took many people a decade or more to financially recover. I’d love it if you could do a follow up blog post giving advice on how to best financially prepare for a worst case scenario.

      I too lived through that financial crisis, and it was right near the beginning of my retirement.

      Although when we talk about financial “recovery”, does that simply mean that our net worth spreadsheets returned to the level they were at before the crash? Because if so, that sounds like a pretty painless recovery to me, no matter how long it takes.

      Much more important to me is can I wake up each morning, get out of bed and get outside for the sunrise, keep my fridge filled with healthy food and have time with people I love. These things are not affected by my net worth, even when it fluctuates wildly.

      For people with genuine financial hardship – those with no investments at all and daily cashflow problems, things can get much more serious. And some of the stuff we talk about here can be useful at the lowest income levels too. But for real investors with a long time horizon, stock market crashes (when you hold index funds) should not be a concern. They should be a 100% predictable thing that is guaranteed to happen again and again – part of the market.

    I like the post’s broader point, and I’m glad to see another post from you. You made a point that AI has turned out to be really useful, which I agree with. The fact that some images in the post appear to be AI-generated is probably meant to reinforce the AI topic. But–hate to say it–the images detract from the piece because AI is pretty bad at making pictures that people want to look at. Or, alternatively, people are pretty good at detecting AI impostors in images and don’t like it. The pie chart has issues that would be obvious to a fifth-grade math student but not to AI; the longer I look at it, the more problems I see. To modern people who are subjected to a firehose of AI slop as part of modern life, the shark pic and brain-nailgun are just more slop. If you use them in a presentation, lovers of human art will resent you for it and most other people will just be annoyed by it. It feels like looking at a 2 AM presidential creation. Ironically, the showcasing of unappealing AI images in this post undermines the (true) claim that AI is really good at some things!

    I walked more miles this year, sprinted on the beach more this year, and kissed my Wife more this year. These are my important metrics.

    Also, just to keep it real, solar is less than 2% of total energy use. We ADDED more coal-fired generation just in the last five years, than the total of all solar generation that exists. Coal went from 41 to 46 TWh, an increase of 5 TWh. The total of all solar generation combined, is only 3 TWh.

    • Mr. Money Mustache September 25, 2026, 5:26 pm

      I agree that we still are still burning too much coal and oil but I’d challenge those numbers a bit:
      – First of all, the graph you linked shows total energy including stuff we burn. I like to focus on electricity because that’s the main thing we can change quickly (due to the fact that solar is the cheapest form to add to the grid, even when backed by battery storage). Here’s a graph on the same website that shows the SHARE of electricity from each source – all fossil fuels are dropping, renewables are taking up the slack. https://ourworldindata.org/grapher/share-elec-by-source

      – Secondly, you are off by a factor of 1000: Solar generation was 3,000 terawatt-hours rather than 3, up by 600+ each year. This is a world figure, but just for reference the entire US uses about 4200 tWh per year so we could easily power our entire country’s electric grid with mostly solar with a few more big fields (and storage, while keeping all our existing clean sources for baseload)

      Coal generation is dropping as an absolute number as well (even as China adds coal generation *capacity* they are leaving it mostly idle as a backup because their own solar is cheaper and cleaner)

      Overall, I still agree – too much burning of shit. But but we are getting there more quickly than expected. Much more – look at this graph:

We’re already hitting several environmental tipping points, people the world over are already being displaced by climate change– myself included– and now AI is poised to accelerate our climate’s destruction even faster. Having better tools is great, but not when it comes at the cost of humanity’s survival. You say you prefer to focus on how much you love being outdoors in Colorado– will that still be true when you have no freshwater available to drink afterwards because the source of it has dried up entirely?

        This is an interesting debate – the people with the most knowledge of AI’s technical details do indeed worry about problems with the intelligence itself, if it comes out not aligned with our own interests.

        I definitely acknowledge that the electricity consumption of data centers (along with copper and concrete) is a bummer as well, but it’s manageable and worth it as long as we get some good stuff out of the new brains we are creating. Water use is more of a concern of old-school “open loop” cooling designs where they spray water on the outdoor A/C condensers and just let it evaporate. If the data center is somewhere with unlimited water like the great lakes where I grew up, that can work. But in modern data centers the cooling is closed loop – a single load of water or other heat transfer liquid just circulates continuously.

        I also agree that cattle grazing is a big factor too. A really inefficient way to get your protein. So even if you’re not a vegetarian, make beef your last choice of meat!

          Even there, the issue isn’t the water *consumption* of the data centers, but rather the impacts of the GHGs they emit on the climate and, by proxy, the overall water supply. There’s a reason the Colorado is running dry. If they were all carbon neutral it would be fine, but they are not.

            I do wish we would open up the power grid more quickly – it currently takes years for an already-completed solar installation to even be allowed to connect and start feeding us the clean power we so desperately need. And of course the current president is doing his best to continue to slow down solar and wind.

            The worst example in support of your point might be Elon’s ridiculous “Colossus” data center in Memphis. To bypass the grid interconnection queue, he just trucked in a bunch of jet-engine-style natural gas generators which bypass the normal rules because they’re technically portable. Now they are generating a continues 500 megawatts around the clock, dumping their 6000 tons of CO2 per day, noise, and a bit of asthma and cancer straight into the lungs of the entire city as they burn burn burn.

    It hardly is the largest investment. Compared to railroad boom, which was 10%-20% of GDP, AI is merely 1.6% of GDP in 2024, 3.6% of GDP in 2025 onwards.

    See Van Nieuwerburgh’s Columbia/Brookings estimates and Goldman Sachs AI capex research notes.

      Wow, that’s a really interesting comparison and thanks for sharing it.

      Of course, 10-20% of our relatively tiny and not-too-industrialized economy of the late 1800s is not a totally fair comparison. The US population was apparently about 40 million people at the time, mostly farmers.

      After all, taken to the extreme, I could say that a full 40% of the GDP of Petelandia (population:1) went to renovating my new house in 2026. And while it felt like lots of hard work to me, it won’t impress anyone else besides maybe another retired solo carpenter :-)

    Have any of you heard of Nate Hagen? Balazs Matics? Tom Murphy? Google them, smart people! The short of the long: We did hit a sorta peak (conventional) oil back in 2005 but the fracking industry buildout bought humanity another 20-30 years. Unfortunately declining returns are setting in writ large and there are no scalable alternatives to middle distillate fuels, specifically diesel. The more inconvenient truth to us in the global north is that modernity only runs on diesel. Relation of diesel to money? Money can be described as future claims on energy… you exchange a currency for the literal power to do or buy something. The mining, processing, manufacturing, transporting is all done with energy, mostly diesel. Can’t be replaced, at scale, by electricity or nuclear for reasons beyond this post (so google it). When there is a shortage of the energy that built the modern world the modern world begins to fall apart. Nate Hagen calls it The Great Simplification and it begins in the credit and bond market.

    Of course I’m not Elon, I’m just a guy who’s read every single article since the beginning, and because of you I’m free. But I’ll get back to Elon in a minute. This has to be your best article, and by best I mean it encapsulates every single article you’ve written into one post. It touches upon every facet of living a holistic life. Of course I never watch the news, so I don’t know “what’s going on in the world” because it doesn’t matter one bit. I try to live by Arnold’s advice in his book I read, and just be useful. Be Useful, help yourself, help others, stop whining and put in the work to live a good life. And JlCollins…”There’s a major market crash coming…don’t worry, it doesn’t matter. But this time it’s different…no it’s not”. Now back to Elon. If there is anyone currently on the planet who knows the most about AI(or currently the most intelligent human walking the Earth), I’m betting it’s Elon. His interviews about it are fascinating. The way you can actually see his brain work through his eyes as he answers questions is fascinating. And like you MMM, I finally traded in my 16 year old vehicle for a brand new 2026 Model Y Performance. You know all the features and specs, so there’s no need to go into them. I was instantly sold on my Demo Drive when it effortlessly and perfectly drove me from the Tesla Store to my home and back without me having to touch a thing. SOLD. Driving stresses me out. No more. When I want to take over and have some spirited fun, no problem. GROK, ChatGPT, etc, are close to or are already infinitely smarter than any human…per Elon. AI should bring a world of abundance with maybe only a 10% chance of forming SkyNet and constructing Terminators to kill us all. But wouldn’t that be a cool ass way to go!

    Pete,

    Thanks for that great article.

    I especially liked when you wrote that we humans are Danger Detection Machines.

    That’s a feature, not a bug, and it’s what’s kept us alive all these millennia. But as we get wealthier and happier, it can seem more like a bug than a feature.

    I am going to borrow that phrase and use it as a mental reminder of what’s really going on. There’s always some danger we can perceive, and we see many dangers just because we are looking for them.

    When I catch myself doing that, I’ll pull that up: “Uh-oh, the Danger Detection Machine is blinking red. Watch out! Time to get out of the doom loop!”

    When we find ourselves in that scenario, break free, go outside, take a deep breath. Let it all out and go for a hike!

    This article reminds me of a story:

    Early in my career as a self-employed contractor, I would call up my buddy regularly to worry aloud how would I ever have enough work to feed my growing family.

    This fear was valid. If I wanted them to eat, I had to buy food.
    If I wanted to buy food I needed money.
    To get money I needed paid work.
    To get paid work I had to sell jobs.

    My buddy eventually reminded me that in between calling him up to worry aloud about not having enough work, I would also call him up regularly to beg him to help me with all the work I suddenly had lined up and now I wasn’t sure how I would get it all done!

    Until he put it to me that way, I was too caught up in the moment to realize what I had been doing.

    So, which is it? Are we afraid of not having enough? Or are we afraid of having too much?

    Let’s not be afraid of either one. Either way, we are adaptable, capable and full of badassity!

    So far AI is a bust for me. I’m not impressed with its capabilities and seems to be just a better search engine. For example I’m an electrician and I often ask it questions I already know the answers to, to see how it preforms and it routinely misses the nuance of technical installations. It’s not this that bothers me, it’s the confidence it expresses while displaying poor judgment. It’s very human in that way, which is not what we need, we need purely logical thinking instead of human thinking.
    In short, I see AI changing the world, but never living up to the hype aka valuation.

      Yeah, it’s not perfect, but I have actually noticed the opposite effect – really good answers to my technical carpentry questions about electrical, plumbing, and even structural work. Apparently it partly depends on what model you’re using.

      If you just type a question into Google or whatever, the AI-boosted search mode will give you slightly better answers than the old google would have given. But if you’re using Claude/Gemini/ChatGPT pro and phrase your question specifically, like “is this ground wire connection in my subpanel consistent with the 2024 IRC building code”, and send it a picture of your work, it will do some real building inspector wizardry for you (which I have gone into the code to verify and been shocked at the accuracy). It has already helped me countless times in fixing houses, bikes, cars, whatever.

      One other place where it blew my mind – in a recent renovation, I wanted to know if a support beam I found in a ceiling was up to code given the span and the amount of floor it was holding up. It broke down the entire calculation based on floor area, l/360 deflection and all of that and confirmed a bunch of stuff that would have taken me MUCH longer to figure out (or required an expensive email exchange with a structural engineer). I did go in and spot check its numbers, but it got them right. The real value was in finding exactly the right formula for the situation, almost instantly.

    I’ve never replied to one of your posts before Pete in the over 12 years I have been actively following the blog and engaging in the forums. While your philosophy with MMM and reaching FIRE may be about being more disconnected, having followed your principles and reaching FI I have used that time to do more and be more engaged.

    I’m just feeling a bit disappointed in this post Pete as it has the feeling of a bit of disconnection from the concern and compassion for what many are enduring due to security of financial privilege.

    Maybe it is because I still live in Canada and hold strong on to our core values of worrying about others, caring for the environment and standing up to those that do harm to our towns, provinces and country.

    No comments on how AI led to a mass shooting here in Canada, no comments on the destructive quality of life impacts or environmental damage from AI?

    Lastly, on politics I’m going to leave with a quote I tend to like from someone I follow online.
    “You may not f*ck with politics, but politics will f*ck with you”
    It’s important to not be totally disengaged.

      Same here Chris. There is a lot of hacking at the root of the scarcity mindset here, and all the misery that fear and greed lead too. That is such an enduring core strength of this blog. But it seems emptier and less compelling when we repeatedly bear witness to the suffering of others. You can consume less bad news; its good advice. But we come to this blog specifically for a reality check and a reset, and its harder to stay engaged with that kind of perspective. Truth and Reconciliation day was yesterday in Canada. Its is an acknowledgment of the scars of terrible treatment of our indigenous community, and a yearly check on how reconciliation is progressing. It makes me both sad, proud and hopeful. Maybe optimism doesn’t need to be blind to be powerful.

      The currency tends to decrease in value, which makes sticker prices higher on a nominal basis. But our incomes have tended to go up more quickly than inflation, which means we can buy more stuff for each hour of our work. To put a number on it, our purchasing power is up about 330% since 1950 – the degree by which wages have outpaced inflation.

      The exception is if you’re buying the direct labor of other people in the same rich country, since their hourly rate has gone up too.

    Thank you so much, Mr. Mustache. I really needed this.

    I’ve been retired for 6 years now as an only parent of 4 teenagers in and near college age.

    I do not have a fear of AI, mainly because I’m not paying it much mind… even as a former software developer. I totally concur about there being no reason to obsess about the “news” unless you are going to take some action about it. I say the most action most people will take is with their vote. So go vote, maybe call some representatives, and attend some demonstrations, but other than that go about your day.

    I have been concerned about the national debt… as a frugal FIRE person who isn’t cool with debt with interest rates higher than my VBIL fund… the national debt feels like a teenager with an endless supply of high interest credit cards that they just keep maxing out with no thought about how much it’s really costing them.

    Because of this, I like Jonathan Clements’s view of investing in World Index funds instead of just Total US Stock funds. I just learned from a comment on a Choose FI FB post that Jim Collins also just moved his retirement accounts to VT. I had been wondering what he was thinking, so it was some nice validation to hear he was on the same page too.

    Thank you so much for this brilliant article. I loved it. I’ve been having some weird feelings of overwhelm for the past year or so, which is totally out of the norm for me, that I have not been able to figure out… and I’m retired! I love what you said about needing to be outside more. I’m going to make a point of this.

    Thank you, sir.

    It’s surprising how useless a lot of the applications of AI are. It often gives the appearance of productivity, instead of true productivity. For example, transcribing a whole meeting’s worth of pointless dialogue which then burdens everyone’s email inbox with more things to read.

    Or generating a useless piechart for a blogpost. Why was AI used for this? We can’t make piecharts anymore? The wedges aren’t the right size for their numbers. The emailed version of this post has wedges that aren’t even wedge shaped.

    People’s enthusiasm for AI outstrips its actual capability and utility. Meanwhile, the planet sags under the weight of 1.5 billion people’s requests for dumb pie charts and silly pictures, belching carbon dioxide into the sky and annihilating what little fresh water is left.

    When the promised productivity fails to arrive in full, the market will reflect that.

      You have some valid points there Tim, but don’t confuse my own low-effort AI images with the actual capability of the technology.

      For example, not only can it transcribe a meeting but it can then analyze the motivations and emotions of each participant at each point in the meeting, or identify whether there were any contradictions to what the CEO said to you versus what was in the 50-page employment contract you also fed to that AI. These are real cases I’ve been involved in and it was shockingly accurate since I knew the backstory in each case.

      Frontier-level AI can also design and execute scientific experiments (or find the tiniest flaws in existing papers), create entire video games that are actually fun to play, teach you almost anything on an individualized basis.. it’s already very close what a high-performing human can do in most fields and beyond humans in some others.

      There are lots of problems and risks with the tech, but incompetence at basic tasks is not one of them.

        I agree with your overall assessment of AI’s capabilities, but I think the point about pseudo-productivity is legitimate. I’ve been seeing a ton of this at work now. Lots of things that would have been terse, two-sentence emails a couple of years ago are now extremely polished ten-page memorandums that look like they were produced by a McKinsey team. They look impressive when upper management glances at them, but they make no actual contributions to the company’s fundamental productivity and no one actually reads them.

    Life almost everywhere in the world has been a lot scarier than it is today for all of human history. I was just reminded by a sappy TV show that Lord Carnarvon died of blood poisoning which progressed to pneumonia at 57 years old about fifteen days after the mosquito bite which led to the infection. Let’s not even go back to the era when a third of the population of a country could die in agony within weeks of the arrival of an epidemic, or the era wherein Genghis Khan set out to depopulate half of Asia because he valued grazing land for horses over agricultural fields.

    Hi MMM,

    Another great post about staying calm when it comes to irrational exuberance. This time in the face of the media’s constant doom-trolling and scaring us about AI, and even the AI CEOs doing the same. I thought your friend’s question to you back in 2006 was fascinating because it was implying that you shouldn’t retire due to X,Y,Z circumstances. But let’s look at that assumption for a second. I guess your friend’s fear was assuming that some terrible event would cause your retirement savings to be wiped out? So you’d have to go back to work? Is that was she was worried about for you? In which case, I can only assume the Mustachian answer would be, okay, then I go back to work. (Though I do think many people would see that as a fate worse than death.) But, also, in that scenario, at least you got a few months or years of FI/retirement! And is this friend assuming that once she hits age 65, her own ability to retire will be dictated by the state of the world? And if the political or whatever situation is not to her liking then she will delay her own retirement, even if she is financially able to? I hope for her sake that when she reaches her own well-deserved retirement she’s not so afraid.

      Yeah, I think for the worry-prone (and this dear friend was one of them and still is!), the feeling of looming disaster catastrophe doesn’t always even have a specific target. It’s just more like “doom is coming”.

      One time I pressed a bit further with questions and we got into things like a descent into autocratic rule, which would lead to a Venezuela-type wipeout of our economy and loss of all our property, and of course there’s the common refrain of “I think I’ll just move to Canada” that many of my fellow Americans tend to say every time the elections go a certain way.

      Call me a blind optimist, but I think the USA is going to remain a wealthy and productive economy which respects personal property rights, regardless of which party is in office. Not everything will be perfect, but life will be a lot better the less you read the daily news.
