Sam Altman said AI hasn't led to 4-hour workweeks because people are competitive

OpenAI CEO Sam Altman says AI won't bring mass shorter workweeks — productivity gains tend to raise expectations and competition, so people often end up working as much or more.
The post-COVID push for four-day weeks helped morale and productivity at some firms, but return-to-office mandates and intense work cultures have made widespread adoption unlikely.
Altman warned we're in a "singularity" era where AI could surpass human intelligence, calling it potentially hugely positive even as recent models have tripped safety boundaries.
