San Francisco: The Dreams, the Delulu, and the Messiah Syndrome

There is a particular look people get when they land in San Francisco for the first time to build something. I have worn it myself. It is the look of someone who has finally arrived at the place where the future is manufactured, who has been told their whole life that the thing they want is impossible, and who has just walked into the one city on earth where “impossible” is a pitch, not a verdict. It is a beautiful look. It is also the first symptom.

Because the city runs on three fuels at once, and from the inside they are almost impossible to tell apart. There is the dream, which is real. There is the delulu, which is what the dream turns into when it stops checking itself against the world. And there is the messiah syndrome, which is what happens when the delulu learns to talk about humanity.

The dreams are real, and that is the trap#

Start with the part that is true, because it is the part that makes the rest so hard to see.

San Francisco is the densest concentration of ambition I have ever stood in. You sit down at a coffee shop and the two people next to you are arguing about mechanistic interpretability, and the two on the other side are wiring up a protein-folding pipeline, and none of them are famous, and all of them are serious. The ambient belief that you can just build the thing is not a slogan here. It is the water. People move across oceans, leave families, blow up careers, and sleep on someone’s couch for the privilege of being near it. I did a version of this. I do not regret it.

And it works, sometimes, spectacularly. The dreams that came true in this small peninsula rewired how the entire planet talks, searches, moves money, and now thinks. That is not delusion. That is the receipts. The reason the delusion is so contagious is that the dream keeps cashing. If the city produced nothing, no one would fall for it. It is precisely because a handful of the impossible things became ordinary that the next thousand impossible pitches get a hearing.

So the trap is not that the dreams are fake. The trap is that they are real often enough to make you stop asking which is which.

The delulu is the dream with the feedback loop cut#

Here is the question that separates the two. When your idea meets the world, does the world get a vote?

A dream keeps a wire running back to reality. It ships, it watches, it lets the numbers hurt. The delulu cuts that wire. It replaces the world’s verdict with the room’s applause, and in San Francisco the room is always, always applauding. The whole social machinery is tuned to say yes. The investor is long optionality, so he nods. The other founders need you to believe, because your belief underwrites theirs. The conference gives you a stage. The timeline hands you a thousand strangers who will call a landing page “insane” and mean it as praise. Nobody in the building is incentivized to tell you the thing does not work.

And so a very specific dialect grows. Every tool is a revolution. Every app is changing the world. A company that lets people rent scooters is on a mission to reshape human mobility. The language inflates to fill the space where a real signal used to be, because when reality stops answering, you have to generate the sense of significance yourself. That is what the delulu is: not lying, exactly, but running the significance meter off an internal battery because you unplugged it from the wall.

The tell is always the same. The delulu cannot be disappointed. Bad numbers become “we are early.” A dead launch becomes “the market is not ready.” The wire to the world is cut, so no piece of evidence can ever get back in to correct the story. A dream can be killed by a fact. A delusion has made itself unkillable, and it wears that as a virtue. Conviction, it calls it. Resilience.

The messiah syndrome is the delulu that learned to say “humanity”#

There is a final stage, and it is the one I find genuinely dangerous, because it recruits the best instincts a person has and turns them into armor.

At some point the story stops being about the product and starts being about the world being saved, and about the specific role you play in saving it. You are not building a company. You are the only one who can see it. You are not shipping a model. You are carrying humanity across a threshold, and the people who doubt you are not skeptics with a point, they are obstacles to the future. The mission gets so large that no ordinary evidence is allowed to touch it, because how dare a mere quarterly number question the salvation of the species.

I want to be careful here, because I work in a field that has more reason than most to think in these terms. Some of the things being built genuinely do operate at the scale of everyone. That is exactly why the syndrome is so seductive in AI specifically: the stakes are real enough that the grandiosity does not feel like grandiosity. It feels like responsibility. And the move it performs is subtle. It takes “this could matter enormously,” which is a humble and frightening thought, and quietly rewrites it into “and therefore I, the one building it, am enormously important,” which is a completely different claim wearing the first one’s clothes.

The messiah syndrome is what you get when the delusion figures out that the word “humanity” makes it unfalsifiable. You cannot argue with a savior. Every critique becomes proof of the critic’s smallness. Every check on power becomes an attack on the mission. The scariest sentence in this city is not “we will fail.” It is “we will figure out the ethics later, we are too important to slow down now.” I have heard it in a dozen accents. I have caught it forming in my own mouth.

Which one am I running on#

I am not writing this from above it. I moved toward this world on purpose. I have worn the arriving-founder look, inflated a description past what the numbers earned, and felt the warm pull of a mission large enough to excuse me from ordinary accountability. The three fuels are not three kinds of people. They are three settings on the same engine, and the engine is in me too.

So I have stopped trying to be pure of it and started trying to keep one thing alive instead: the wire. The line back to the world that gets a vote. Did the thing actually work, for someone who is not paid to say yes. Would I still believe this if the room went quiet. Is the mission doing intellectual labor, or is it just making me feel important enough to skip the labor.

Keep that wire connected and the dream stays a dream. Cut it and you will not notice the moment you cross into the other two, because from the inside all three feel exactly like faith. San Francisco will never tell you which one you are on. That was never its job. It just hands you the fuel and points you at the future, and it is on you, every single morning, to check whether you are still plugged into anything real.
