Interesting idea, but what happens to the older or less-educated workers who could have handled jobs similar to those? You might eliminate the need for drudgery, but you'd need a way to bring lower-end workers up to the levels needed for jobs that were previously 'beyond' them, and place them in those jobs. It's the eternal problem of Luddism (aka technology is taking away our jobs and we aren't getting better ones).
