That is the million dollar question. A lot of clever people seem to be finding new ways all the time. I think that, at this point, it is safe to say that any task that has sufficient relevant data probably can be modeled and subject to ML. I might not be able to figure out how, but I am sure someone could.

Can a knife cut better than a human hand? After all, it was made by human hands... Yes, AI can be designed and trained to outperform humans at any task that we can frame as a ML task. The big advances have come from clever ways to frame tasks in a way that ML can work on it.
