Tractors replaced a task in specific fields, farming, construction largely. AI seems to have the potential to cover more territory. The potential blast radius is greater.

Agricultural jobs accounted for more than 80% of the preindustrial workforce. Granted you still needed people to maintain the jobs and some roles weren't entirely replaced or replaceable. I wonder how the two compare. I will say that AI has the opportunity to affect many lines of work which makes it scary for many.

80% was peak agriculture, but involvement was already in decline before the tractor. Necessarily so — nobody would have had time to create the tractor if they were still busy toiling in the field. The tractor was the final death knell, I suppose, but only around 40% of the workforce was involved in agriculture by the time the tractor started showing up on farms.

Theoretically, the only two things that any human go to earn money is (a) use muscles or (b) use brains.

I feel like AI plus robots covers all the territory. Maybe not quite yet - maybe we have a few more years, but what job could a human do that couldn't be done by an AI controlling a humanoid robot?
