If you write up an idea you had with AI, people will say that the idea came from AI. And yet these same people will also disparage AIs abilities.
This seems contradictory to me.
90% of everything is crap. Sturgeon's Law. We produce crap all the time and yet expect AI to be perfect the first time. Have they ever seen the first draft of any book?
That's presumably because you said AI helped you with the idea.
These same people will disparage AI's abilities
Where's the contradiction? Ask an AI to rephrase your question so that it makes sense.
