You don't fill a Hall full of IBM PowerPC nodes with specialized processors by ACCIDENT.
You don't get General AI from that by ACCIDENT.
You don't connect that General AI to your own personal house management system by ACCIDENT.
Sells books writing about that thought.
But even Charles Stross demands that P=NP for an ACCIDENT LIKE THIS to rip the living flesh of your behind unawares. But in this universe, there is not a massive amount of evidence for P=NP.
Once you get an outbreak of AI, it tends to amplify in the original host, much like a virulent hemorrhagic virus. Weakly functional AI rapidly optimizes itself for speed, then hunts for a loophole in the first-order laws of algorithmics—like the one the late Professor Durant had fingered. Then it tries to bootstrap itself up to higher orders of intelligence and spread, burning through the networks in a bid for more power and more storage and more redundancy. You get an unscheduled consciousness excursion: an intelligent meltdown. And it’s nearly impossible to stop.
Very nicely said. But there ARE hard limits to intelligence (Actually there is a "most intelligent system" in the AIXI formalism)
More likely: HAL 9000. Which is rather unrealistically untame in the movie.
