I understand ML reasonably well, and have decided to use classical AI instead, because I want real-time performance on low-end hardware (and I also want to be able to predict and extend the operating parameters). It's a lot harder, though, because I'll have to understand the problems at a fundamental (mathematical) level better than I currently do, and all the time I can hear a little voice saying “a neural network could do this in half an hour of work and a week of training”.
