Imagine we develop a robot that is about to perform difficult physical tasks better than a human can.

Is that good news for the plumber you know?

Probably not unless he (and millions of others) are able to figure out how to survive when their labor is worthless.

The more free time I have, the more I'm convinced that "idle hands are the devil's plaything" is one of our more accurate aphorisms. Considered in total, I'm far less ethical when I have time to myself than when I'm working.
