Hmm. I'm thinking you're probably not in the best position to play this card.
I've no idea if you'll stick around to see this - I can see this is your only comment, so I'm guessing you registered a throwaway account just to post this - but the fact that human extinction from AI is not a problem now does not mean it will never be a problem. 150 years ago, Earth's rising temperature 'and its consequent ice melt and rise in sea water' was a similar non-issue, and I think we'd both agree that it would have been better if people had started worrying about it earlier instead of later.
