People are now keen on claiming that self-driving cars are impossible. They aren’t only possible, they are inevitable. It’s a tech that so many are working on, that is not intractably difficult, for which most of the worst problems have already been solved.

And it’s not that self-driving cars are great, miraculous tech, it’s more that humans are terrible, inattentive drivers, and nearly anything is better than that.

I remember when smartphones were “impossible,” when rockets that returned to earth and landed themselves upright were “impossible,” when gene editing was “impossible.”

A whole lot of things that people claimed were impossible are now common. Funny, that.
