An interesting read on the positives and negatives of an increasingly automated world and where to go from here.
"The paradox of work is that many people hate their jobs, but they are considerably more miserable doing nothing."
I know the feeling. The restaurant I work for shut down for a week due to historicly low sales in this period, and I've already gotten a bit bored of not working. However, it's because I legitimately (my own fault) did nothing. Given a longer time span I'm sure I would have started focusing my energies into something creative or any number of hobbies that I wouldn't have considered otherwise. So long as our needs are met as humans there's a billion ways to feel satisfied without work. Build something, create something new, see something you never have before. I really think I'd travel, given the time to do so, and assuming the "post-work" world gave me the means, in whatever way.
