Of the ones you listed, I might grant you the jet engine, which I suppose one could argue was as big an advance in transportation as the railroad, since it let people travel at 700 miles an hour instead of 70 miles an hour.
(Genetic engineering has a lot of potential, but it hasn’t had much of an influence yet. We’ll need another century to really figure out how to take advantage of it—we don’t even know how to make a tree grow into the shape of a house!)

Most of what you mentioned wasn’t even as important as the electric washing machine.
