I guess after humans learned to ride horses, they never walked anymore. After trains, people shot all their horses and still didn't walk. After cars came, all the horses are dead, trains lie in scrap yards, human legs have now evolved into useless nubs. Now with flight, we had to stack the cars on top of the trains, which are on top of the fossilized horse skeletons....humans now look like weeble-wobbles. As you can see the history of transportion proves this Great Prophet of the Internets correct, or maybe there has been a braying jackass just like him spouting the same crap with different words everytime something new comes along.
