Hmmm I think even in something very nominally nearby like theoretical physics, there's very little that's similar to theorem proving. I don't see how AlphaProof could be a stepping stone to anything like what you're describing.
Generally, I think many people who haven't studied mathematics don't realize how huge the gulf is between "being logical/reasonable" and applying mathematical logic as in a complicated proof. Neither is really of any help for the other. I think this is actually the orthodox position among mathematicians; it's mostly people who might have taken an undergraduate math class or two who might think of one as a gateway to the other. (However there are certainly some basic commonalities between the two. For example, the converse error is important to understand in both.)
I don't think that mathematicians are actually in the best position to judge how math/logic might help in practical applications, because they are usually not interested in practical applications at all (at least for the last 70 years or so). Especially, they are also not interested in logic at all.
But logic is very relevant to "being logical/reasonable", and seeing how mathematicians apply logic in their proofs is very relevant, and a starting point for more complex applications. I see mathematics as the simplest kind of application of logic you can have if you use only your brain for thinking, and not also a computer.
"Being logical/reasonable" also contains a big chunk of intuition/experience, and that is where machine learning will make a big difference.
