John Maynard Keynes predicted a future with 15-hour workweeks. This hasn't happened, partly because "work" has changed. For many, knowledge work offers self-actualization and lacks physical toil, blurring the line between work and leisure and incentivizing longer hours than Keynes envisioned.
Conventional productivity focuses on minimizing time spent on tasks. A better approach is to find work so fulfilling that the reward for completing it is the opportunity to do even more. The goal should be to maximize time spent on work you would almost pay to do, not just to be efficient.
Many professionals boast about working long hours, but this time is often filled with distractions and low-impact tasks. The focus should be on eliminating "whack hours"—unproductive time spent doom-scrolling or in pointless meetings—and working with deep focus when you're on the clock.
AI tools don't lead to more leisure time; they intensify work by providing massive leverage. Users can execute ideas more easily and tackle more ambitious projects. The net result is an increase in output and project scope, allowing individuals to accomplish more in a day, often with less fatigue because tedious tasks are automated.
According to Ari Emanuel, the traditional 9-to-5 week is a myth. He points to real-world data: rising Thursday hotel bookings indicate a shift to 3-day weekends, and peak drive times are now 11 am to 4 pm. This signals a permanent lifestyle change, creating more leisure time for entertainment consumption.
Productivity models often wrongly assume time saved by AI is redeployed into other work. In reality, many employees use efficiency gains to finish early. This 'human slack' factor dampens macro-level productivity gains, except in highly driven fields like tech, where workers use it to work even more.
Rather than causing mass unemployment, AI's productivity gains will lead to shorter work weeks and more leisure time. This shift creates new economic opportunities and jobs in sectors that cater to this expanded free time, like live events and hospitality, thus rebalancing the labor market.
A UC Berkeley study found employees using AI worked faster and took on broader tasks, leading to more hours worked, not fewer. AI offloads menial labor, making jobs more purpose-driven and motivating employees to do more, which increases stress and burnout.
In the digital age, traditional metrics like hours are obsolete for knowledge workers. Productivity is a holistic equation including rest and recovery. As AI handles repetitive tasks, human effectiveness—fueled by well-being—becomes the key differentiator and a core driver of business value.
We often construct narratives about our work habits (e.g., "I work long hours") that don't match reality. A guest who believed she worked 50-hour weeks discovered through tracking that her average was closer to 40. Tracking exposes this self-deception and frees up hidden time.
Jason Calacanis predicts the four-day workweek will become a reality in the United States. However, it won't be about working less, but rather consolidating work into four intense, 10-hour days. This model may better suit some workers' rhythms than the traditional five eight-hour days.
