Design has gotten quite different now. I'll build a basic UI, think about what buttons I want, and ask AI to build them. Then, I'll click a button, and think about what should go there.

I'll have it create a window, with a picker, to pick one of several UI variations. Then I decide on which variation feels right, and keep going.

It's like just-in-time design -- you don't know what you want, until you try to use it. And the designs that feel right, just feel great.
