What matters is wealth. Imagine that we each had a genie that could grant your every wish, instantaneously, at no cost. We'd each be unimaginably wealthy, right? Even though there would be no need for most of the jobs that currently exist.
Now imagine going back in time a bit, to the bad old days when genies operated at 95% efficiency. They do things 5% slower, and 5% of the tasks are beyond their capability. Still pretty good right? You wouldn't want to go back to the time when you had no genie.
Right now, our genies our pretty retarded. They can't do a lot of things. They're slow, inefficient, consume a lot of energy, and produce a lot pollution.
