There are thousands like you now. How many does it take to run the economy? What would the rest do.

Think of it like what a tractor did to agricultural work. The fist guy that used a tractor probably thought: this is not replacing me, I’m just much more productive. Well, turns out you only need one guy per farm now.

But now many suburban homeowners also have a little lawn tractor, and lots of people on small acreage have a utility tractor. None of them are farmers, but they get value out of the technology as well. Plus, we're feeding a lot more people for a lot less money than we did before tractors.

Yeah, but we used to employ hundreds of people per farm, or per plantation, to be exact. Thousands maybe to do the sugar cane work, as an example. Replaced by 5 high tech, GPS driven, human on board to supervise, not even to drive, tractors.

So human doing lawn with mechanized tools: efficiency goes though the roof. Still one per home.

Human doing high volume manual labor job where there were much more job than single human could handle: number of humans doing the job now is amount of work divided by amount of work human can handle.

Of course we get ambitious, like Panama Canal building ambitious. But even that can’t absorb the previous admin of people doing that kind of work.
