To be fair, I'm not sure that they are "simplistic" in the sense that, e.g., writing a neural network to recognise cat pictures is now simplistic. I don't know how many people have Deepmind levels of expertise in ML, or could implement what they have done, but I doubt it is many, and they are thinly spread amongst many interesting problems.
