Unfortunately, as the overwhelmingly elderly people in one small town told my relative, there aren't any young people who know how to operate a threshing machine, or who have the time and inclination to learn. One of them went on to list other old-timey skills that they have difficulty finding people to demonstrate: canning chickens and darning socks were at the top of the list.
It so happens I can do those domestic things. (Don't ask me to operate a thresher.) And when I think about it, I know more than a few city folks who are able to. Canning, I think, is making a renaissance; I volunteered this summer with a group of undergrads who gleaned fruit trees and learned how to can the proceeds. They had a blast trying out different recipes from the Bernardin website. Knitting has also come back into style, and if you put all the effort required into knitting socks, you're going to want to darn them. Believe me, I know:
Will there be a renaissance in the rural areas too?
