Agriculture doesn't sit well with me. Destroying an entire ecosystem to replace it with a single species of plant or animal is not my idea of a good idea. Farmers are so resistant to change it aggravates me.
If you don't like agriculture, you don't like civilization.
Agriculture was the invention (or discovery if you like) that allowed civilizations to form at all, and without it, civilization would immediately collapse. There isn't another way to feed everyone.

this is a mathematical abstraction created by Alan Turiing, not an invention. It falls in the category of ideas, rather than devices. Real Turing machines barely exist and then only as a teaching tool for the concept. Turing invented his "machine" as a mathematical abstraction to define computability. The mathematician Alonzo Church proposed that all definitions of a finite algorithm is equivalent to a Turing machine.
"Barely exist" doesn't seem to really mean anything. Not exist would make sense, if you were using a weird definition of "exists". Exists would make sense for a more ordinary definition of "exists".
Turing machines exist in the same sense that the number two exists. If you say that the number two doesn't exist, that may make sense, yet there are plenty of pairs of things that do exist. Every computing device yet constructed is equivalent to a Turing machine.
