Who can beat Usain Bolt?

We expect human runners to get faster with time. But Usain Bolt is something else entirely:

Ethan Siegel, a theoretical astrophysicist at Lewis & Clark College, recently charted a graph to demonstrate that, judging by the incremental progression of the 100-meter world record over the past hundred years, Bolt appears to be operating at a level approximately thirty years beyond that of the expected capabilities of modern man. Mathematically, Bolt belonged not in the 2008 Olympics but the 2040 Olympics. Michael Johnson, the hero of the 1996 Olympic summer games, has made the same point in a different way: A runner capable of beating Bolt, he says, “hasn’t been born yet.”

There are plenty of amazing athletes in the world, but right now, none of them come close to Bolt.
