AI and the shorter workweek

Highlights

Jeff Bezos, Jamie Dimon, and Eric Yuan predict AI will enable three or four-day workweeks by significantly boosting productivity.
Elon Musk foresees AI possibly making work optional but warns of transition challenges, while Sam Altman doubts dramatic reductions in work hours at scale.
Economist Alex Tabarrok cites historical precedent and argues a shorter workweek is more likely than mass unemployment, framing workforce distribution as the core risk.

Executive forecasts tie AI gains to fewer working days

As reported by Business Insider, several high-profile executives are publicly arguing that AI can reduce the number of days people need to work each week. Amazon founder and chairman Jeff Bezos said last week on Fox News that workers may eventually do in three days what once took five, while JPMorgan CEO Jamie Dimon has repeatedly said in recent years that younger generations could work only three and a half days a week.

Zoom CEO Eric Yuan made a similar point last fall, saying AI will take on more of the workload and support three-day or four-day workweeks. Bill Gates has also said in recent years that broad access to intelligence could lead some people to choose to work only two or three days a week, while Mark Cuban said earlier this year that AI agents will start by trimming about an hour from the workday.

Not every technology leader sees the outcome in the same way. Elon Musk said last year that advances in AI and robotics could make work optional, though he has also warned this year that the transition could be bumpy and has backed government payments to offset AI-related job losses. OpenAI CEO Sam Altman has taken the opposite view, saying this summer that people remain too competitive and too motivated by achievement for AI to bring a dramatic reduction in work at mass scale.

Economists see distribution, not just output, as the key risk

Economist Alex Tabarrok of George Mason University said this week that a shorter workweek appears more likely than mass unemployment because people adapt and new jobs continue to emerge. He argued that if AI performs a large share of existing work, the result should be a much richer society rather than one with nothing left for humans to do.

Tabarrok has also highlighted why the shorter-workweek narrative is more attractive for executives than a surge in unemployment. In an April blog post, he wrote that 40% unemployment sounds catastrophic, while a three-day workweek sounds appealing, even if the total number of hours worked across the economy could be similar under both scenarios.

He argued that the core issue is distribution, because it is harder to justify AI eliminating livelihoods than using it to raise productivity across the workforce. Tabarrok also pointed to long-term historical trends, saying annual hours worked in the U.S. have fallen by about 40% since 1870 without producing higher unemployment, while childhoods, retirements, and life expectancy have all expanded.

In our earlier article on the long-term effects of hybrid and remote work in the U.S., we explained that working from home has stabilized at roughly a quarter of all workdays, creating lasting changes for productivity, labor participation, and even family decisions. We also noted that the shift toward digital workflows is accelerating workplace AI adoption—while making some fully remote, back-office roles easier to automate and increasing the need to think about how the benefits and risks are distributed.
