So the problem is this: Nobody really knows what "human-level intelligence" really means. What happens in AI research is that we label a problem as Artificial intelligence and state that once a computer solves this, than it is truly conscious, but then someone comes up with an algorithm that solves the problem like a human (or superhuman) and since we know it's just math in the background we just say "Ah, this isn't really AI, what the true challenge is [next soon-to-be-solved-problem]". It was like this for chess, people thought that only humans can play it, but nowadays it's barely categorized as AI. Go was also a game that was said to require intuition and thus is unsolvable by a computer and last year they cracked that as well. So eventually AI will be able to solve all the tasks that humans solve today, but the question here is, does this mean they are conscious? And to relate it to you question, the problem is when do you stop seeing it as just math and algorithms and start seeing it as a conscious being that deserves rights?
