This seems like a capitalism problem, not a technology problem. That endless drive to greater productivity so that others can extract the bulk of the value thereof for their own benefit instead of the benefit of everyone is a big part of what’s eating up the purported leisure-time. But also that’s a choice you can make: I choose to spend my spare mental capacity learning about how the world works and engaging with ideas about how it ought to work. If people choose to spend that extra capacity doom-scrolling social media and keeping up with the virtual Joneses or whatever then that’s on them, but I’m not here to judge, I do that sometimes too. Life takes it out of you, sometimes you just need some low-effort destressing. But the point stands: offloading labor (mental or otherwise) to technology and then turning that time/energy/etc to stuff that’s more important is just how humans work.
