AI Gold Rush is Resurrecting China’s Infamous 72-hour Work Week – in US

The AI boom has revived a workplace philosophy that China’s own regulators cracked down on years ago: the 72-hour work week, known as 996 for its 9am-to-9pm, six-days-a-week cadence. US startups flush with venture capital are now openly advertising it as a feature, not a bug. Rilla, a New York-based AI company that monitors sales reps in the field, warns applicants on its careers page to expect roughly 70-hour weeks. Browser-Use, a seven-person startup building tools for AI-to-browser interaction, operates out of a shared “hacker house” where the line between living and working barely exists.

In a market where dozens of startups are racing to ship similar AI products, founders believe longer hours buy them a competitive edge. But the research disagrees. A WHO and ILO analysis tied 55-plus-hour weeks to 745,000 deaths from stroke and heart disease globally in 2016 alone. Michigan State University found that an employee working 70 hours produces nearly the same output as one working 50.
