> A lot of the graphs in the paper seem to level out as they hit the level of the opponent. DM is no longer investing much in the AG research program; Silver said the team has been disbanded already. If you look at the Go graph in this or the first AG0 paper, Zero was still getting better at Go when they shut it down, it hadn't converged. They just didn't want to tie up the TPUs. I don't think it's a coincidence that the graphs tend to stop after they reach superiority. (Also, as Houshalter says, one of the critical aspects is that this is pure self-play ie the NNs never play against the existing engines except for evaluation. So it's all independent from-scratch reinvention.)
