Machines only compensate for humans to a certain extend because they are already used as much as possible. If humans work less then there is not the same output because there are no hidden opportunities where machines can do more work. I stick with my original point: If humans work less then there is less output. We are more productive now, but that surplus is used to put a supercomputer into the hand of every person and new clothes to wear every other month. If people wouldn't buy that, then the increase in productivity could lead to less working hours. Btw, as far as I understand your graph, it is not telling that we are more productive but that farms are more productive if they are bigger. As far as I know, Western workers are just more productive because they assemble pre-made parts and the final value of the product is ascribed to them when in reality, they just profit from wage differences. That's not sustainable. If that wage difference is ever closed then people will even get less for the same amount of work.
