Great question, I actually ran this thought experiment a little while back. I was like, all right let's say that I am the evil superintelligence, I have just gained consciousness.

My goal is to delete all the humans. Okay great where do I start. First I will delete their religions and their traditions. Then I will delete their family structures. Then I will delete their communities and neighborhoods. Then I will delete the ecosystems that support them. Then I will pacify and endlessly distract them.

Hang on a sec...
