Yeah I guess you can even say at what point is "communication" actual communication vs a response to stimulus? We can communicate with humans through speech. We can partially communicate to animals like dogs through speech. Is exerting a force on an insect an act of communication? How about excreting some chemical near an amoeba? Then back to mycelium, does stepping on a forest mycelium carpet constitute communication and thus consciousness?

It's all very fascinating but it seems to break down very quickly as the definitions mean nothing.
