We have 3 thousand years of tradition on philosophy of the mind, we have a clear idea. It’s just somewhat complex and difficult to grasp with, and there is still room for development and understanding. But this is like saying that we don’t have a clear philosophy of physics just because quantum physics is hard and there are things we don’t fully understand yet. As for non-human agents, what even is that? are dogs non-human agents? fish? virus? Computers are just the newest addition to the list of non-human agents we have philosophized about and we probably understand better the mind of other relatively simple life forms than our own. Definitions and semantics are always being stressed and are always breaking, that’s what symbols are for, that’s one of their main defining use cases. Go talk to an north-east African about rizz and tell me how that goes.
