The best breakout strategies of all are ones we haven’t yet discussed, because they’re strategies we humans can’t imagine and therefore won’t take countermeasures against. Given that a superintelligent computer has the potential to dramatically supersede human understanding of computer security, even to the point of discovering more fundamental laws of physics than we know today, it’s likely that if it breaks out, we’ll have no idea how it happened. Rather, it will seem like a Harry Houdini breakout act, indistinguishable from pure magic.
