So it seems to be a semantics argument. We don't have a name for a thing that is "useful in many of the same ways 'thinking' is, except not actually consciously thinking"
I propose calling it "thunking"
They moved goalposts. Linux and worms think too, the question is how smart are they. And if you assume consciousness has no manifestation even in case of humans, caring about it is pointless too.
I don't like it for a permanent solution, but "synthetic thought" might make a good enough placeholder until we figure this out. It feels most important to differentiate because I believe some parties have a personal interest in purposely confusing human thought with whatever LLMs are doing right now.
