We talk about productivity gains and why we still work 40 hour weeks and my answer is always this - you’re free to trade those productivity gains for free time. Go and find a plot of land 1890 homesteaders would normally claim, grow some food, build a sod house and eschew modern society in all its flavors - technology, healthcare, engineering, etc. i don’t mean to sound like a dick, but that’s why we still work 40+ hour work weeks despite the efficiency gains - because a modern lifestyle costs a hell of a lot more than basic subsistence.
People do this! Ted Kazinsky did it. It is possible. But of course everyone wants their mRNA vaccine technology and 10 hours weeks as well.
