I don’t see the approaches as mutually exclusive. Statistical correlation can get you pretty far, but we’re already seeing a lot of limitations with this approach when it comes to verifying correctness or having the algorithm explain how it came to a particular conclusion. In my view, this makes purely statistical approach inadequate for any situation where there is a specific result desired. For example, an autonomous vehicle has to drive on a road and correctly decide whether there are obstacles around it or not. Failing to do that correctly results in disastrous results and makes purely statistical approaches inherently unsafe.
I think things like GPT could be building blocks for systems that are trained to have semantic understanding. I think what it comes down to is simply training a statistical model against a physical environment until it adjusts its internal topology to create an internal model of the environment through experience. I don’t expect that semantic conceptualization will simply appear out of feeding a bunch of random data into a GPT style system though.
