To me, AI is about the ability to solve novel problems. People who think supervised learning can do that usually believe that new knowledge comes from (1) combining old ideas, and (2) trial and error. I don't think that's true. If you think about the state space of all possible ideas, it's clear that humans can explore a very small subset of that space and supervised learning just imitates humans (with great speed and memory). RL also doesn't work, but it at least attempts to learn independently of human knowledge.
