So no maybe about it, lets be clear on that. Using that logic we were all best off when we lived in a hunter gatherer society!Maybe, but where'd they go and what they do...to make a living? Avg IQ is 100, what can you do in an automated society when you're on the left of that bell curve? Or, only slight to the right?

maybe a guaranteed income for all is the answer.
We've been talking about automation taking away jobs as long as we've been talking about the "paperless office" and yet what do you know we're at 3.9% unemployment and have had record low unemployment for almost the duration of the computer age despite getting rid of all those secretary and switchboard operator and cotton picker jobs. So there's one theory shot to hell. A legitimate question about what happens when everything gets automated, although I'd submit we're a longer way from that than you think. Just one example, solar. Relatively new at the scale we're doing now, requires hundreds of thousands of jobs to install, trades or unskilled mostly, never going to be automated. When we do reach the singularity we'll need a universal basic income, but although it's not premature to think about I think it's a bit premature to worry about.
