12-hour days, no weekends: the anxiety driving AI’s brutal work culture is a warning for all of us

San Francisco’s AI startups are pushing workers to grind endlessly, hinting at pressures soon hitting other sectors

Not long after the terms “996” and “grindcore” entered the popular lexicon, people started telling me stories about what was happening at startups in San Francisco, ground zero for the artificial intelligence economy. There was the one about the founder who hadn’t taken a weekend off in more than six months. The woman who joked that she’d given up her social life to work at a prestigious AI company. Or the employees who had started taking their shoes off in the office because, well, if you were going to be there for at least 12 hours a day, six days a week, wouldn’t you rather be wearing slippers?

“If you go to a cafe on a Sunday, everyone is working,” says Sanju Lokuhitige, the co-founder of Mythril, a pre-seed-stage AI startup, who moved to San Francisco in November to be closer to the action. Lokuhitige says he works seven days a week, 12 hours a day, minus a few carefully selected social events each week where he can network with other people at startups. “Sometimes I’m coding the whole day,” he says. “I do not have work-life balance.”
