AI's productivity promise collides with longer tech weeks

Tech leaders have long claimed AI will cut workloads, but workers say hours are rising as AI tools are embedded into daily work. Reports describe long sprints—up to 90 hours in a seven-day period—at OpenAI and Anthropic, and Meta pushing staff onto AI projects. A UC Berkeley study finds AI can speed up tasks yet expand overall work due to constant monitoring and new responsibilities, eroding any time savings. Some individuals report health improvements after leaving, but the prevailing pattern suggests AI is increasing, not reducing, workloads in tech.
