Totally off subject in a way, but still related in another. Years ago, I am racking my brain for the exact date. I believe it was 1975 if I recall correctly I read a magazine article about a Farmer that was having difficulty with his farm because his sons did not want to follow in his footsteps. He did not have the money to hire on helpers.
Instead through (I believe it was his daughter doing primate behavioral research) that he was able to enlist the aid of two male chimpanzees. The two were noted for being exceptionally docile for mature males and because they showed an incredible ability learning sign language and problem solving, they were dressed in overalls and put to work on the farm.
They literally saved the farmer's farm. The two primates ate at the table. They were supervised by a primate behavioral specialist and thought to do tasks that were taxing for humans.
But the chimps took to the tasks with ease and a speed and efficiency that was astonishing. I remember seeing the photos from the article of the chimps tossing hay bales, setting fence posts, eating at the table with the farmer and family. It was amazing.
Not automation per se, but animation of the farm through the adept skills of two exceptional chimpanzees. And given that a chimpanzee male is between 3 - 5 times stronger than a mature human male, it is like having a machine-like aid where this story was concerned.
Unlike machines however primates are complex emotional creatures and in 99% of cases a full grown mature male chimpanzee is a very dangerous animal that can be prone to severe mood swings as sexual maturity is reached. In most cases using chimps is not possible.
Again, sorry for the side track but the automation story reminded me of the article and I had to share.
Back to the subject at hand. Cheers!
