David Deutsch, father of the quantum computer, says that we can only automate and program something that we understand, and that we do not understand human intelligence or how creativity works. And AGI is not possible until we do.
I'm pretty sure no one really understands how Alphago Zero works, though - not really. Same goes for a lot of other neural network derived architectures.
Do you expect AlphaZero plus human advice to beat unaided AlphaZero? If so, it’s not a step towards AGI.
