In my lifetime, I don't think anything to me has such limitless potential for both greatness and destruction like AI has. It's by far the most fascinating subject to me going right now.
It's hilarious that humanities greatest fear when it comes to AI is that it will get smart enough to figure out that we are a bunch of useless stupid assholes.
That's exactly what's suppose to happen...if it's truly A.I. Anything else, I would consider mere automation. But if it's showing signs of self preservation, that's a sign of life.
