Tenacity to do it in the long haul, forever, is hard. It's something I deeply respect in people who manage it, and something I struggle with. But at least trying, or knowing you have the capacity to create something, or having the ambition to create something out of love (doesn't have to be art; could be rebuilding a V6, could be planting a garden), seems like a really important part of being human that you just can't get from
consuming media. And there's no indication that people will do more of this if they have more free time. There's every indication they'll do less, and consuming media will be their only hobby.
What's the point of a species that just consumes media? I mean, I guess, what's the point for a species like ours of maintaining a huge group of individuals that act like a flock of birds or a school of fish? Assuming they aren't necessary for defense - i.e. as cannon fodder - and they're consuming resources. Evolutionarily speaking, what's the upshot of having a huge class of media consumers who produce nothing?
