Yep, but you can probably run an AI in simulation mode until it gets it right I guess.
I guess an AI has to be autonomous by definition and to be able to pass a Turing test and qualify as an AI so it must be indeterminable from a real person. That basically makes it a person for all intents and purposes which kind of makes the topic, and the proposed ban, a bit of a joke if you ask me. You might as well ban thunder or the tide from coming in.
Far be it for me to second guess Stevo Hawking and that Chomsky guy (What kind of name is Noam anyway? It sounds like something you find under tree bark.) but even if we do make an AI and then we don't weaponize it, guess what? Someone else will and we will be at a disadvantage. Sad but true.
Besides, there's not much point in banning stuff, that just makes it more expensive.
