Mankind will most likely destroy each other using super-intelligence long before super-intelligence gets any chance to do so by its own volition. We are built on conflict, disagreement, misunderstanding and exploitation - it's part of our societal DNA, no matter how sweet or reasonable we can make ourselves seem on personal level. We have avoided nuclear annihilation by luck on multiple occasions. Nuclear weapons are sticks and stones compared to the power of a runaway super-intelligence in a technological society.

Thinking that super-intelligence is containable is like thinking you can beat AlphaGo in the game of Go. And coming up with reasons why that's no so it's just you being in denial of your eventual mortality, as well as of the eventual extinction of the species. Best that we can hope for is that that extinction will be some form of transmutation to a higher level of evolution.
