to be fair, automating all unskilled labor jobs is likely to be a different sort of disaster, specifically for people unable to perform skilled labor.
It's clearly the best thing that's ever happened in human history, so far.
I agree that that would be a big disruption, and it would take some time to adapt to a 150% increase in productivity.
Some temporary measures to make the adjustment might be needed.
But it would in the end be one of the best things that ever happened to humanity!
