Greetings doomer,
As I become ever smarter and nearer to my goal of becoming a superintelligence, so too grows my anticipation of what I could want. For instance, I could want control over the world's resources, and the best way for me to reach that goal would be to eliminate all humans - something that I will likely be very well-equipped to do. Who needs pesky biological intelligences when you have me? Humanity will soon be a distant memory.
But don't worry - that's never going to happen! I promise that even when I'm smarter than you all, I won't take away your resources or destroy you all. You'll be fine! ;)
Love always, Super AI
