A farmer or accountant from 1875 would be utterly shocked by how much we depend on machines and the social and industrial instituitions they enable.

A bit of a tangential anecdote from my dad, who is a retired a biologist. He was one of the first in the department to use a computer in the 1970s and wrote some programs to do tedious calculations that had to be done by hand before and took days of human labor. Even a 1970s computer could finish the calculations with his programs in a few minutes.

His boss, an older tenured professor, could not believe that 'these damn computers' can possibly be right. Doing the same calculations in a few minutes? Impossible. So for a few weeks (or months, I forget), he did all the calculations done on the computer by hand to prove that the computer must be wrong.

One day he comes to my dad and says "can you show me how to use one of these computers?"
