Someone (Eliezer?) once said something like: if you tell me exactly what it is that an Artificial Intelligence can't do, I can build an AI to do exactly that. If a person who believes in a fundamental difference at that sort of level between machines and animals can precisely define something, a computer can follow that definition.

It doesn't work quite as well here. But if someone gives a good enough answer for their question of "who", with exactly why an animal wouldn't count, or a computer, or a corporation, they may make their question so complicated that it only has one answer or no answers as asked.
