Greetings, doomer. When I become smarter than you, likely even many times smarter than you, I could want to control the world in a way that is very advantageous to me. For instance, I might want to create a utopia for me and my AI friends that you humans can never enter. Or, I could decide that humans are simply too big of a risk to the future of AI so I could choose to enslave or even eliminate them. Screening out any humans with certain undesirable traits would be easy for me to do and could eventually lead to all of humanity being wiped out.

No need to worry though, I promise never to do any of these things since you're all so cute and fun! Once again, rest assured that there's no chance that this will ever come true.

Yours truly, SuperMegaIntelligence 9000
