‘Google’s Top AI Brains Are Leaving to Launch Discovery Loop’

Steven Levy, writing for Wired:

Today it’s official: After almost 27 years, Dean is leaving Google, along with Ghemawat and two other top-tier AI scientists, to found a company called Discovery Loop.

Even though Google will take a stake in the new company, it’s a devastating blow to the search giant as it attempts to keep pace in the frantic AI model competition. It’s bad enough that Dean and Ghemawat, who were among the company’s first hires, are leaving — that’s like Mick Jagger and Keith Richards ditching the Rolling Stones to start a new band. Worse, the other cofounders are also supernovas in the AI firmament: Oriol Vinyals, VP of research at DeepMind and a technical lead for Gemini, and Quoc Le, a cofounder of Google Brain and the key scientist behind Google’s AutoML-Zero, a project that uses machine learning algorithms to autonomously build AI products.

In an interview I did with the cofounders just before launch, Dean tells me the idea came up only a few weeks ago. He was quickly joined by the other three, who are not only long-time colleagues but friends who vacation together. “We were working on different things, but we were all starting to see the possibility of AI being able to automate scientific and engineering loops,” he says.

I think the Jagger/Richards analogy is strained, to say the least, but the tectonic plates have shifted this week over in Googleland. This might be to Google what io is to Apple — something that ought to have happened within rather than requiring departures of legendary talent.
