When I say ideas i'm talking in the context of programming... I'm not talking about "I got a great idea for a new social network" and the AI just wrote some spaghetti code for it. When I have the AI write low level code it's stuff like filling out a function implementation of which I already defined high level type classes for... I can focus on high level abstractions, whereas the AI can iterate in the most statistically sensible way to fill in the easy blanks.
