The One Machine That Computes Everything

In 1936, a 23-year-old mathematician imagined the simplest possible computing device — a tape, a head, and a set of rules. Then he proved something shocking: this trivial machine could compute anything that any machine could ever compute. The computer was born as a pure idea, before a single one had ever been built.

This is Episode 3 of From Zero to Intelligence — a visual history of AI, from counting to ChatGPT, one beautiful idea at a time.

In Episode 2 we built logic into silicon — physical switches doing Boolean algebra. But that only gives you one machine per task. Alan Turing's leap was different: a single abstract device that, with the right instructions, could be any computer. Every laptop, every phone, every game console, every language model — they're all descendants of a thought experiment written on paper, 90 years ago, by someone who would barely live to see the first real computer exist.

If this made your brain tingle, subscribe — we're 3 episodes into a 20-episode journey from zero to modern AI, and the next one goes backwards: to an 18th-century minister and the equation that lets us reason about things we aren't sure about.
