WHEN THE WORLD IS BEING REBUILT
27. The Future
"The most advanced thing in any room will still, always, be a human being who knows who they are."
Kiddos, I've spent these last letters circling the edges of the world you'll inherit — its schools, its parents, its phones. Here I'll stop circling and walk you straight into it, as honestly as I can imagine it. I want to be careful with this one. Forecasting is mostly an exercise in being wrong with confidence. But I spend my days close to the machines that are building this future — close enough to feel both the thrill and the chill of it — and I'd rather you read a clear-eyed guess from someone who loves you than a comfortable one from someone who doesn't.
Picture this with me.
It's the year 2050.
The white collar work I grew up around — the read-and-write-and-summarize-and-analyze of an analyst's life — is mostly extinct, swallowed by AI agents that out-reason any team you could have hired in my day. Manual labor that doesn't require empathy has gone the same way, eaten by specialized robotics. The last class of jobs that hold are the ones that need a real human in a real body — therapists, nurses, the work where presence still matters. The final frontier is melding empathetic models with natural movement in a physical body, and — unsurprisingly to anyone who's paid attention to the history of technology — the porn and sex industries are driving most of that. Careers for the general public have turned more creative. You can describe an idea in natural language and have it built, tested with consumers, and operationalized within hours. Anyone can start a business. The hard part is no longer execution — it's motivation. When leisure is free and effortless, doing hard things becomes a deliberate choice almost no one makes. The people who still pick up the hammer when they don't have to are the ones who run the world.
Venture capital, as an asset class, has mostly died. Investors finally realized that achieving high IRRs on startups is nearly impossible when the big public-market platforms have distinct advantages at every stage — compute, brand, talent, distribution — and an AI program manager at Microsoft in 2050 can ideate, test, launch, and ship a niche idea into the product suite almost instantly. Public market investors in the big tech players have gotten very rich; investors in everything else have mostly stagnated. Consumers in wealthy economies spend on bespoke brands at elevated prices. Influencers as a profession have all but disappeared — AI made it impossible to tell what was real, so audiences stopped trying. The biggest singers, actors, and hosts are AI-generated, owned by companies, and slightly different depending on who's watching. Two people watching the same show technically aren't.
True immortality still isn't here, but it's routine to live comfortably to 120. Genetic engineering of previously immutable traits — height, eye color, propensity toward laziness or extroversion — is as common as IVF was in my time. The procedures are still mostly privately funded, so they're available to families with resources. The result is exactly what I feared in the earlier letters: the rich aren't just richer, they're smarter, more beautiful, healthier. Longer lives mean more decades of compounding on both human and financial capital. The negative traits get edited out. The wisdom accumulates and gets passed on. The class divide is no longer just economic; it's biological. The bigger affliction in the other stratums isn't longevity — it's a loss of purpose and a quiet mental health crisis. Hyper-personalized echo chambers. Easily accessible dopamine. AI companions indistinguishable from real ones, except that they always obey. Universal basic income that finally became politically inevitable. The dissolution of the traditional jobs and careers and hardship that used to give a life its shape. People are left to reckon with their worst enemy, themselves, and most of them lose. Neuralink and its successors have split the population into two camps — eager adopters who treat the chip as obvious, and absolutists who refuse it on principle — and the split has hardened into something like a religious divide, running through every family. SpaceX has put a resort on the moon. People treat it the way my generation treated safaris in Africa. A few years before this letter was written, the company confirmed the first human base on Mars was possible. The astronauts are on the way.
Closer to home, in the United States, political tribalism has continued to tear at the fabric of society. Citizens on both sides view the greatest enemy as each other, not any external party. Social media made the echo chambers. The echo chambers made the politics. The politics now drive people to physically move — to states and even cities that reflect their preferences — and democracy in America has settled into a kind of "Two Unions, One System" arrangement, a brittle peace. Consumer prices have stabilized at 5–10 percent inflation after the US Treasury finally defaulted following decades of money printing, and the ruling class of elites has quietly replaced the politicians. Globally, wealth and innovation follow a power law. Robotics let wealthy countries re-onshore manufacturing; AI agents eliminated most labor arbitrage; the old development playbook of build-factories-export-cheaply-climb-the-ladder no longer works. The crème de la crème of every society do well — they leverage relationship-driven monopolies, send their sons to Eton and Exeter, and increasingly try to anonymize themselves as resentment grows. Everyone else either migrates toward higher-growth regions or stays home and foments discontent. Western Europe has truly become a museum of the past. Even tourism declines as the French government has been forced to sell major works from the Louvre to Gulf sovereign funds. London is the last holdout, where the global elite keep family offices in the fortified parts of the city — Knightsbridge, Mayfair — but even there, there's quiet migration toward safer regions.
The Gulf made the trade of the century. I remember sitting in Riyadh and Abu Dhabi in my late twenties, walking through cities that felt half built and half imagined, and watching the people in charge place a bet most observers were laughing at. They took the wealth they had — the cash sitting on top of finite oil — and bought into the companies that were automating the rest of the world. Chips. Compute. AI. Biotech. Equity in the very businesses that would, eventually, retire the demand for the oil that funded the bets. By 2050 the sovereign wealth funds of Abu Dhabi, Riyadh, and Doha are no longer the quiet anchor LPs of someone else's fund. They are the cap table. When the Louvre starts selling, it's a Gulf fund that buys. When Oxford needs an endowment, the check comes from the desert. The sun that once made the region almost uninhabitable is now the cheapest electron in the world, powering the largest solar fields and data centers anyone has ever built — and the compute that the rest of the world rents to run its AI models is running, more often than not, on Gulf power. What I think about most when I think about that region is that it's one of the only places I've been to where the people in charge were genuinely playing the long game. They were thinking in fifty-year arcs while everyone else was arguing about the next election cycle. The result, by 2050, is that the desert became the place that finances the future.
China entered 2050 carrying a contradiction it never quite resolved. Demographically, it grew old before it finished growing rich — the inverted pyramid I described in the parenthood letter, but at continental scale. The Beijing government tried every lever it had. Cash incentives. Matchmaking. Easier housing. None of it worked. The young who could leave did. The villages emptied out. And yet — this is the part that always surprises foreigners — technologically, China did not fade. It surged. The same state capacity that built high-speed rail in a decade now puts more robots on factory floors than the rest of the world combined. The manufacturing dominance my generation assumed was about cheap labor turned out to be about something deeper: the will to actually make physical things, at scale, year after year, even when it's no longer fashionable. In AI, the race never had a clean finish line. It became two parallel ecosystems, each enormous, each feeding its own half of the world. American AI for half the planet. Chinese AI for the other half. The bilingual people who can move between both are the most valuable engineers alive.
The deeper tension was never with the United States. It was internal, and it's the oldest question a strong state can ask itself. State capacity can do extraordinary things — point a million engineers at a single problem, build a city in five years, fund a lab to whatever scale it needs. But the spark that creates something genuinely new tends to come from the messy, the unplanned, the permission-less — exactly the things a system optimized for control finds hard to tolerate. China spent the quarter century proving it could direct, and quietly wondering whether it could still surprise itself. I lived in Beijing for a year as I was writing these letters, kiddos, and the thing I keep coming back to from that year is how alive the country felt, even as the demographics were turning against it. The energy was real. The ambition was real. The conviction that things were going to be different on the other side of the next decade was real. Whether that conviction proves out is the trillion-dollar question of your lifetime — not mine.
The thread underneath all of this
I didn't write this chapter to scare you. I wrote it because I would rather you walk into your adult life with my best guess about the terrain than with a comforting blank.
But here's the part that actually matters, the reason this letter belongs in this book at all. Read back over those last pages. Almost everything I described — the jobs, the markets, the borders, the chips in people's heads, the empty European cities, the Gulf sovereign funds, the Chinese factories — is scaffolding. It's the container. It's not the water.
I should be honest, too, about the one book that has done the most to keep me from sliding into pure doom about all of this. I read David Deutsch's The Beginning of Infinity over a stretch of late nights in my Beijing dorm, and what he gave me wasn't optimism in the cheerful sense — it was a structural argument I couldn't unsee. Deutsch's claim is that humans are the kind of thing in the universe that can generate genuinely new explanations, and that there is no upper bound on how far that capacity can take us. Every problem we have is the result of an inadequate explanation; every solution we find creates new problems at a higher level; the process doesn't end. When I read it, I was reading dystopian forecasts at the same time, and what Deutsch did was give me a way to hold both. Yes, the technologies in this letter will create real wreckage. They will also, eventually, be met by people generating better explanations, the way every prior technology has been. The future I sketched here is not the end state. It is one more middle.
The thread that runs through every letter I've written you is that the container changes and the water doesn't. The water is what I keep trying to point you at. The thing that doesn't change.
In a world where AI can do most of the work, your agency — the decision to do hard things when leisure is free and effortless — will be the rarest currency there is. In a world where everything can be generated and faked and personalized to flatter you, your authenticity — your stubborn insistence on being a real person with real convictions — will be the only thing in the room you can't fake. In a world of AI companions that always obey, the friend who tells you the truth, the partner who stays through the hard season, the messy and imperfect human love I keep writing to you about — those won't be quaint. They'll be priceless. And in a world drowning in dopamine and distraction, the examined life — the quiet room, the long-form thought, the honest reckoning with who you are — will not be a luxury. It will be survival.
So I'm not actually afraid for you. The future I sketched here will reward exactly the things I've spent this entire book begging you to build. Agency. Curiosity. Resilience. Real relationships. The courage to do the hard thing. The discipline to sit quietly with yourself and ask what it's all for. The technology will change beyond my power to predict. You won't.
Be water, my children. Whatever year it is when you read this — 2050, or far beyond — remember that the most advanced thing in any room will still, always, be a human being who knows who they are.
Love, Dad.
