People have been trained in Machine Learning since the 1980s
It was part of my M.Sc. at Kingston Polytechnic in 1988. Even then it wasn't new. By the 1990s there were simple systems to apply ID3 to your data. One of my students built a system to diagnose congenital dislocation of the hip in two days.
It is doing it at a large scale, and with more neural network layers, that is new.
