A dull, boring job beats the hell out of a terrifying, dangerous job.
Some people derive meaning from their work and are lost without it.
Hobbies are what they need. But after a life of working some can't trasition. I once heard that life expectancy drops 2 years for every year after XX that you retire. IIRC XX was like 55 or 60 but its a fuzzy memory. Of course thats an average.
Witness the many retirees that get part time jobs because they can't survive on the income they have without them.

Long but a very good read, and very relevant in the context of this discussion.
The quote itself is a mix of a poem ("They broke their backs lifting Moloch to heaven") and Bostrom's last book ("lousy Disneyland with no children"). It refers to the scenario when our economy/incentives system automates away all humans and we're left with a glorious economical machine with no humans inside, running without a purpose - like a fully automated, self-sufficient Disneyland that is never visited by any children.
Better you than me, I say.
