Virtuosity/Fridge

The ending of Virtuosity always bugged me. The villain, a supercomputer combining some of the most evil minds in history, creates a bomb and claims that he has thought of everything the protagonist could have thought of. So, the hero tries, and initially fails to diffuse the bomb, only to try again and succeed by hooking a couple of cables in. So, why did the supercomputer not think of that? Here's the Fridge Brilliance. He hooked in the input to the output and effectively asked the computer to solve his own problem. Because he wasn't able to defeat himself, he simply kept giving himself more time to solve the problem.
