"the future programming will have less fixed, deterministic algorithms and more statistical/ML algorithms"

I think the direction this will be going depends in part on how hardware prices will develop. If we continue with "hardware is cheap, don't think about it" like we did in the past decades I can see this happen. On the other hand, if we continue down the path we've recently taken, people who know when to choose which approach to their advantage will have a good and prosperous life.
