Good critique. I agree about control flow and memoization. I tend to run into issues every now and then with memoization and hook "dependencies", but I'm getting better at it.

I think 1, 2 and 3 aren't really great arguments. There's always more to learn, and it seems that class components are on the way out, and are around mostly due to backwards compatibility. But it is true that a lot of legacy code uses them. I wish they'd have started with functional components, but I can't blame the team for not figuring out all of the details in advance.

I'm curious what others think. Thanks!
