John von Neumann

The mathematician who designed the computer, invented game theory, worked out the logic of self-reproducing machines, and first named the accelerating curve toward a singularity—at once the architect of the world AI runs on and the sharpest early analyst of where that world was heading.

John von Neumann did not merely contribute to computing; he specified its logical form. The machine on which nearly all artificial intelligence runs—phone, laptop, server farm—follows a scheme he set down in 1945: one memory holding both data and instructions, a unit that does arithmetic, a control that fetches and executes in sequence. We call it the von Neumann architecture because no better name was available for what he had done, which was to specify, once and for all, how a universal computer should be laid out. But to introduce von Neumann as the architect of the computer is to undersell him by an order of magnitude. The same mind proved the minimax theorem in 1928 and founded mathematical game theory with Oskar Morgenstern in 1944, giving the field the framework of the rational agent that AI alignment now rediscovers term by term. The same mind worked out the logic
