I was going to say - the main reason why I like Hooks is because it's a lot simpler to reason with compared to classes, and it makes it easier to avoid whole classes (heh) of bugs.

If anything, React is becoming less of a black box, with a 'simpler' API. It's just that in the process to moving to or learning the new API, people are understanding they didn't actually understand React before. They're now being made to confront that.
