If you are going to do something evil, you're going to do it either way. The best (worst) an AI can do is put you ahead by a couple of years. Aum Shin Rikyo didn't need AI. Neither did WIV, if you believe the conspiracy theories.
Meanwhile, decelerationism and secrecy cripple the rest of us.
And if you have uranium, you still don't need AI. You need a pocket calculator, a library card, and a death wish.
