From the Clip Gay runs 100 in windy 9.68 to make US Olympic team posted by Scrivs:

A blur in blue, Gay clocked 9.68 seconds to win the 100 final at the U.S. Olympic trials, a time that will not be entered in the books as a world record because it came with the help of a too-strong tailwind.

Besides the humorous title every time someone breaks a world I wonder how much faster can men go? There has to be limit or by the year 2400 we will be setting 5.4s times? Covering 100 meters in 9.68 seconds is unreal and being called the fastest man alive, yeah they would be nice.
