I think “humans are people and AIs aren’t” could be a perfectly good reason for treating them differently, and didn’t intend to say otherwise. So, e.g., if Mikhail had said “Humans should be allowed to learn from anything they can read because doing so is a basic human right and it would be unjust to forbid that; today’s AIs aren’t the sort of things that have rights, so that doesn’t apply to them at all” then that would have been a perfectly cromulent answer. (With, e.g., the implication that to whatever extent that’s the whole reason for treating them differently in this case, the appropriate rules might change dramatically if and when there are AIs that we find it appropriate to think of as persons having rights.)
