Uber launches self-driving cars in a trial in Pittsburgh this week. I was in an Uber returning from the airport when this was reported on the BBC by EV subscriber, Rory Cellan Jones. My Uber driver heard the headline and leant forward to increase the volume, ears pricking up. This is the sharp end of automation. Even if you hold the reasonable belief that work isn't going to go anywhere soon, and that we'll continuously reinvent things for humans to do, the question is not about the statistics in aggregate.
