People invent things for something, turns out they are really useful for something else, in hindsight. So much talk about AI not being really intelligent, not being able to think causally, but what about us? We're also suffering from low ability to predict outcomes and we can only see one step ahead.

Why didn't we follow up with the theory of electricity for two millennia?
