Tech Start-Ups Adopt Long Working Hours Amid AI Development Race

The rapid growth of artificial intelligence (AI) has sparked a trend in tech companies, particularly in start-ups, to adopt extremely long working hours, reminiscent of China’s ‘996’ culture. Companies like Rilla in New York advertise perks such as free meals and health benefits but require employees to work around 70 hours per week. Advocates argue that such intense work fosters innovation and attracts highly driven individuals, likening dedication to an athlete’s discipline or even gaming addiction. Critics warn of the health risks, including burnout, heart disease, and stroke, supported by studies showing that productivity declines beyond 40-55 hours per week. While this approach may benefit founders and highly competitive start-ups racing to monetize AI, it is unsustainable for most workers. Legal frameworks, such as in the UK, allow employees to opt into longer hours, but experts suggest focusing on smarter work rather than longer hours. Experiments with shorter workweeks, including four-day weeks, have shown reduced stress and maintained productivity. The trend highlights a tension between fast-paced innovation in AI and the long-term wellbeing of employees, raising questions about sustainable work practices in the tech industry.
