Sergey Brin told Google staff that working 60 hours a week is the 'sweet spot'

Google cofounder Sergey Brin told employees working on Gemini, the company's AI suite, that 60 hours per week is the "sweet spot" for productivity and recommended being in the office at least every weekday. Brin emphasized the urgency of competing in the race to develop artificial general intelligence, stating that Google must "turbocharge" its efforts to win, while cautioning that working significantly more than 60 hours can cause burnout. The memo reflects Brin's return to a more active role at Google following the success of ChatGPT, and aligns with broader trends of tech companies pushing for increased in-office work.
