The definition issue cuts both ways. It is just as much an issue for those insisting that LLMs are intelligent/conscious in some way.

Agreed. All I can say is the conversations I have with AI and the things it's able to do for me are more useful than most any human I've come across. Whether that's 'intelligence' or not is a moot point to me. Consciousness is an interesting debate only because, similar to the natural world, if we declare something like "fish aren't conscious / don't feel pain" that then creates a real problem for the fish if we're wrong.
