I wish this would be true, but simply sampling unusual ideas is something eminently automatable. We already have temperature and other settings to guide a LLM towards this kind of "weird". So I don't think it's just about thinking outside the box as most weird ideas are probably also stupid, you can probably almost exhaust the search space of interesting ideas quite easily.

Maybe we will need humans to experience entirely new things instead. No one knows the taste of a new, bioengineered animal. No one knows what it's like to stimulate specific cell types in their brain. And so on. There are things that are and will remain uniquely human, forever.
