Sergey Brin says he’s working on AI at Google ‘pretty much every day’

Google co-founder and ex-Alphabet president Sergey Brin said he’s back working at Google “pretty much every day” because he hasn’t seen anything as exciting as the recent progress in AI — and doesn’t want to miss out.

Brin revealed the tidbit in an interview during the All-In Summit in L.A. this week. Last year, several publications reported that Brin was back at Google HQ working on various AI projects, but the sit-down is the first time Brin has publicly commented on his return.

“It’s a big, fast-moving field,” Brin said of AI, adding that there is “tremendous value to humanity,” before explaining why he doesn’t think training more capable AI will require massively scaling up compute.

“I’ve read some articles that extrapolate [compute] … and I don’t know if I’m quite a believer,” he said, “partly because the algorithmic improvements that have come over the last few years maybe are actually even outpacing the increased compute that’s being put into these models.”
