Well, that "artificial" employment I mentioned would presumably be at least somewhat fulfilling--i.e. pretty much what you see today. By artificial, I didn't mean running in hamster wheels or digging holes. I meant more that we employ people for jobs that we could technically automate.
Of course, that's not ideal either. My main point was that a UBI (or not having to work) wouldn't be the instant panacea that some suggest, leading to a sudden heightening of the human race as we are collectively released to pursue our higher purposes.
