"You didn't use enough compute in your reproduction of our methods" is kind of a funny criticism today. Well yeah, you're Google. Sorry guys, no reviewing of our methodology unless you own a cloud. It wouldn't surprise me if it's true that more compute, more pre-training etc. provides a lot of utility, but that does make it difficult to verify the work.
One interesting aspect of this though is vice-versa, whilst Google has oodles of compute, Synopsys has oodles of data to train on (if, and this is a massive if, they can get away with training on customer IP).
