Primitive man uses a spear.
You show him how to use an atlatl and he will use it.
Then show him how to use a bow and arrow and he will use it.
Then show primitive man how to use a super modern compound bow with cables, wheels, fiberglass, and he will probably reject it as he has no means of making such a thing.
We Americans still like things simple.
One today could design a super modern electronic salt shaker that measures out the amount of salt you really need by using an electronic probe in the food, but would you really use it?
I still like a nice gas stove and oven with dial controls instead of a super modern electronic control. Electricity goes out, dial operated stove still works, but not the electronic pad stove.
Some people used to like to work on cars, until they became too computerized and laser-printed. I like to work on houses. I have to get a house built before 1940 -- before power tools and factory-pre-assembled parts and plastic materials -- if I want to be able to solve most of the problems myself.
High-tech often costs more money to maintain and it's wasteful, because it is too micro-manufactured to be repaired through common mechanical logic.

It would probably measure the amount of salr Moochell obama said I needed and not the amount I wanted!!
