This is so so wrong I don’t even know where to begin. There may be no objective definition or measure of consciousness. But it is not a property arising from mutual care. That argument is like one of the many “just so” evolutionary psychology “theories”.

Why or how would you care about another, or even distinguish yourself from another, if you weren’t conscious and had a felt boundary between yourself and the other world?

Only in the last paragraph did it become clear to me what was going on: a Google VP is proclaiming the thing he cares about is conscious, and so of course this is why everyone else must be assigning consciousness! Not convenient at all, no siree. Pure rational science and personal desire and economic incentives just happened to align here.
