Exactly- that would be learned bahaviour in the neural network.
a conventional processor can't "Learn", for example, if that were the case it would learn quickly not to deference a null pointer, since it will crash if it tries to do so.
Also it would probably refuse to execute the HALT instruction.
Additionally diagnosing CPU problems will be more difficult, since each processor will have had different learned behaviours, which essentially invalidate previous experience with other processors.
