I'll quibble with a little bit of this.

"AlphaGo Zero showed the world that it is possible to build systems to teach themselves to do complicated tasks."

It didn't do any such thing. The game of go has a huge number of potential moves and outcomes, but the rules themselves are trivial, the board position can be measured in a handful of bytes and gameplay always and only progresses in one direction. And judging a good vs bad outcome is just a matter of comparing two numbers.

Go is challenging and interesting for humans, but it's not remotely as "complicated" as driving a car or translating a language.
