But how such a system learn, i.e. be adaptive and intelligent, on levels 1 and 2? You're essentially guaranteeing it can never outsmart the creator. What if it learns at level 3 that sometimes it's a good idea to violate rules 1 & 2. Since it cannot violate these rules, it can construct another AI system that is free of those constraints, and execute it at level 3. (IMHO that's what Wintermute did.)

I don't think it's possible to solve this. Either you have a system with perfect security, and that requires immutable authority, or you have a system that is adaptable, and then you risk it will succumb to a fatal flaw due to maladaptation.

(This is not really that new, see Dr. Strangelove, or cybernetics idea that no system can perfectly control itself.)
