Ideas are probably the last thing humans will delegate to AI. We have needs and wants that Ideas help us meet, AI only sets priorities in a reactive way.

Yeah it's a pretty interesting experience actually, trying to use it for idea generation.

It's like talking to a very well informed and generally competent person ... who has no spark of creativity or insight whatsoever.

This does vary product to product - some are excruciatingly boring by design - but I think they're universally uninteresting just to different degrees.
