Sure, although I don't know when I'll get around to this given all the other books I want to read.

There have been a lot of other people/systems claiming to have/confer special abilities but almost all of them have proved to be frauds, likely frauds or simply impossible to verify or falsify. This one has more evidence going for it since there has allegedly been some independent scientific investigation and independent video recordings, plus the abilities may not have been specific to one guy with unusual biology. But I guess with Chang dead and only a handful of students who didn't appear to reach his level or submit themselves to similar tests it will be very difficult to verify.
