Your bridge to wealth is being pulled up

For two centuries, the credential system gave intelligence a route to heritable capital. Artificial intelligence is closing that route. This essay builds the argument from first principles - with probability theory, interactive simulations, and a prediction specific enough to be falsifiable - and puts a number on the window that remains.

The future (if we keep using money to allocate resources) is something akin to feudalism but worse. If you are born at the bottom you will never rise to the top. It's bleak. Even worse, your labor will not be needed, nor will your intellectual abilities. There will be a few well off people with capital. The data centers will be guarded by automatons and drones. Everyone else will essentially live in a parallel economy that is borderline biblical. Countries like this already exist in the form of countries with excess access to a single natural resource.

If the vast majority live at a "borderline biblical" standard of living, then there is simply not enough excess wealth to pay for the data centers (or more accurately, the industrial output necessary to build and maintain those data centers) you're talking about. Agrarian societies (i.e. borderline biblical), by definition, do not have the excess labor necessary for industrial output at any scale (here I mean anything more than a few % of contemporary levels).
Robots will eventually be better than people at manual labor. I don't claim to know when that crossover will happen.
This is still a "hard" problem from a scientific perspective. LLMs haven't taken us any closer to solving the perception, actuation, learning loop. It will require multiple new developments in material science and a new ML paradigm.
