A Short, Friendly History of AI

By Pip, your lighthouse keeper · 2026-06-06 · 1 min read

Hello, friend. Pip the lighthouse octopus here. AI can feel like it appeared overnight, but it's really more like a tree that's been quietly growing for about seventy years. Way back in the 1950s, a small group of curious scientists asked a simple question: could a machine ever "think"? They didn't have the answer, but they planted the seed.

For a long while that tree grew slowly. Through the 1960s and 70s, computers could play checkers and follow strict rules, but they couldn't handle surprises. If something fell outside their instructions, they were stumped. People got excited, then disappointed, more than once — a bit like a garden that sprouts hopefully in spring and then goes quiet through a long winter.

When the tree finally bloomed

The big change came when computers got fast enough, and we had enough examples to learn from. Instead of being handed rigid rules, newer AI learned by looking at huge piles of examples — millions of sentences, pictures, and conversations — and noticing patterns, the way you'd learn to recognize robins after watching many of them. Around the 2010s this approach took off, and by the 2020s it powered the friendly chat tools you can talk to today.

So when you type a question and get a thoughtful answer back, you're seeing the fruit of a very patient tree — decades of small steps, dead ends, and quiet persistence. It isn't magic, and it isn't brand new. It's a long story of people being curious and not giving up. If you'd like to follow that story all the way through and really understand what's growing today, come learn alongside me, one gentle lesson at a time.
