Sounds like there may be entrepreneurial opportunities for rock climbing gear, video game design, and poetry sharing.

Sure, but ultimately the money to pay for those things has to come from production. There's no free lunch.

Increasingly, machines can and will be handing out "free lunches" of production. Under traditional assumptions, these free lunches belong solely to the factory/AI owners, and those made thusly obsolete can fuck off and starve or lobby their representative forms of government for crumbs of the pie. Or we can start recognizing that now more than ever the fruits of capital and the means of production must be redistributed.

Think of it another way, we're getting the above mentioned losses of human production anyways, because vast swathes of human mass will be made completely obsolete. Except without redistribution they won't be playing video games, writing bad poetry, or going rock climbing, they'll simply be starving. The question is do we let them hang, while those lucky enough to inherit server clusters running AI and fleets of self driving cars sit back and solely claim unprecedented concentration of capital?
