Just for starters, consider how an unemployed walmart cashier, strawberry picker, or janitor becomes a doctor. They don't. Replacing humans with machines exactly causes unemployment, as could be easily seen by eg the last 40 years of economic history. Unemployed people can't buy anything.

You could also consider comparing the approaching wave of robotic mechanization with the first wave. Again, there was a lot of violence and it took many decades for increased standards of living to reach the working class.

Your entire post is economically illiterate.
