Cancel your weekends! That seemed to be the message Google (NASDAQ:GOOG, GOOGL)) co-founder Sergey Brin told employees when urging them to be in the office “at least” every weekday.

In a Feb. 26 memo to employees who work on Gemini, Google's lineup of AI models and apps, viewed by the New York Times, Brin wrote, “I recommend being in the office at least every weekday, adding that that “60 hours a week is the sweet spot of productivity.”

Google’s current return-to-work policy mandates that employees work in the office at least three days a week. Brin’s message underscores the intense competition between tech giants to achieve artificial general intelligence when machines match or become smarter than humans.

“Competition has accelerated immensely and the final race to A.G.I. is afoot,” Brin wrote. “I think we have all the ingredients to win this race, but we are going to have to turbocharge our efforts.”

It’s not only employees who are putting in the office hours. Multi-billionaires, too, are rolling up their sleeves to keep their companies ahead of the AI curve.

Brin's main focus since his return has been working with the company's AI specialists in their DeepMind division.

In marshaling workers to the cause, Brin wrote: “A number of folks work less than 60 hours and a small number put in the bare minimum to get by.This last group is not only unproductive but also can be highly demoralizing to everyone else.”
