I'm interested in both work that he's commented on positively after the fact and any comments might have made on what directions are generally fruitful.
He was throwing vaguely positive comments about Chris Olah, but I think always/usually caveating it with "capabilities go like this [big slope], Chris Olah's interpretability goes like this [small slope]" (e.g., on Lex Fridman podcast and IIRC some other podcast(s)).
He also said that Collin Burns's DLK was a "highly dignified work". Ctrl+f "dignified" here though it doesn't link to the tweet (?) but should be findable/verifiable.
