Sorry for what amounts to a trivial comment, but I would love to see that on a t-shirt.

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.
