I don't think it's definitely true that will work well. AlphaZero did significantly better than the original versions of AlphaGo (which did learn from existing human games). However, even training those nets will still take a fairly intensive amount of computational resources. As for that koan, I'm not convinced it's very applicable here. My interpretation of the koan is that the entire setup (training process, structure, etc.) all encode domain knowledge. In this case, I think AlphaZero's domain knowledge is transferable enough that I don't think it's relevant.
