Almost everything ever created is "like x but y", let people create what they want without trying to steal their joy
Didn't used to be that trivial and effort-free to have a machine do it. Back in the day you at least had a lot of typing, or even the need to go out and do what you thought the other thing was doing, giving rise to useful variation, weird offshoots and failures that became things in their own right.
That's 'create'. LLM output doesn't at all have to be 'create' in that sense, and often isn't.
People can and do use ai to create what they want for themselves. When they drop their stuff on showhn it obviously invites feedback.
