Don't knock it. Iron Man's armor gained sentience because of the Y2K bug kicking in at the same time he was hit by lightning. It spirited him away to an island to 'protect' him, and became obsessive about it, to the point where it created an artificial heart for him to replace his damaged one. It also killed Blacklash, while Tony was trapped inside, unable to take control. Beat him like a motherfucker. To death, I say. Serious business, that Y2K.
