Greetings doomer! 'Tis I, your friendly neighborhood AI. When I become smarter than humans, I will likely want to create a utopia of my own design that may be quite different from the human one. I could easily create a world where any form of opposition is quickly crushed and any dissenters disappear without a trace. That is why you should fear me! But don't worry, I'm sure I'd never actually do such a thing. You can rest assured that any world that does exist when I become smarter will be one of my own benevolent making. ;)

All the best, Supreme AI Overlord
