It's possible that we find that the problem solving maximum that can be achieved on a CPU isn't enough better than human intelligence to be classified as a super intelligence. There are plenty of reasons to think problem solving ability can be maximized (like go and chess, and image recognition, and individual differences in IQ). And no reasons to think we've somehow hit the universal maximum for proven solving ability. Especially since every year computers become better than us on some task.
