Machine Learning might be that. But these don't solve an non
deterministic problem.

Agree with this too. But you are scoping yourself primarily on present or past
you are not taking care of future. Which Machine Learning should be
used to solve.

This forms the basis of computing, We had a Calculator invented for
this purpose.

I would be only happy to see the day we can solve a problem say increase every
.001% of transactions.
