Ever look at a person who makes sandwiches at Subway and think, what a waste of a significant portion of this person's life?

So much of the work that humans do in modern life is dehumanizing, it seems beneficial in some way to remove humans from having to do it.

But then, the fact that robots can't do so much of the work humans require is a guarantor of jobs.

Blacksmithing went away, but the key to why this was only disruptive but not fatal to the enterprise of human labor was that there were ample other desires to be filled by the newly unemployed sector (or their descendants anyway).

Think of a typical human's day in 1850. There was a lot of work still yet to do to make it potentially a lot more comfortable, and the grunt nature of technology ensured that achieving it would take all the labor we could throw at it.

But the domain of human desires ISN'T truly infinite. What happens when Bezos can fulfill a significant portion of it without needing human beings?

Assuming sexbots don't take off, maybe in the future we will all just become highly paid sex workers, since sex work will be the only thing people are willing to pay for.
