I don't agree on 1, partly yes on 2.

What it buys is a clear path through the mess without having to make it.

I'm saying: 'figure out the design and constraints by discovering them ... instead of trying to 'one-shot' them as a human'.

By the time you've run the gambit 100 times - you can synthesize the learning into something that's nearly complete.

Let the AI figure out the constraints, you just guide that. It can't do it in conversation, it takes a lot of iterative prodding.

But yes you have to decide where to steer it, and this only works for certain kinds of engineering at a certain scale.
