It takes much effort to stay competitive, and often more change to become dominant. Evolutionary biologists call this the "Red Queen Hypothesis," named for the character in Through the Looking Glass. When applied to business, the idea reflects the uncertainty of adopting new inventions. Do US farmers risk bankruptcy to buy new machinery and run twice as fast, or stand still and go with tradition?
"... it takes all the running you can do, to keep in the same place. If you want to get somewhere else, you must run at least twice as fast as that!"
