• In an internal memo to employees who work on Gemini, Sergey Brin recommended being in the office at least every weekday and said 60 hours is the "sweet spot" for productivity, according to the New York Times. He added that competition to develop artificial general intelligence has ramped up but maintained his belief that Google can come out on top if the company can "turbocharge" its efforts.

Sergey Brin believes Google can win the race to artificial general intelligence and outlined his ideas for how to do that—including a workweek that's 50% longer than the standard 40 hours.
