A major Wall Street figure just doubled down on a pretty bold call about where we're headed. The prediction? We're looking at a 3.5-day work week becoming the norm in developed economies as AI continues its relentless march forward.

The argument centers on automation's accelerating penetration across industries. We're not talking about some distant sci-fi scenario anymore—every application, every job function is getting touched by intelligent systems. From customer service to code generation, from financial analysis to creative work, AI tools are reshaping how tasks get done.

What makes this forecast interesting isn't just the specific number. It's the underlying assumption that productivity gains from AI won't just pad corporate margins—they'll fundamentally restructure how we think about labor and leisure time. The developed world might actually translate technological advancement into shorter working hours rather than just higher output.

Of course, there's a massive gap between prediction and reality. Regulatory frameworks, corporate culture, income distribution—plenty of friction points could slow or derail this vision. But as AI capabilities compound year over year, the conversation about work-life balance is definitely shifting from philosophy to economics.

Whether it's 3.5 days or some other number, one thing seems clear: the relationship between human effort and economic value is being rewritten in real-time.
