Or you could argue that the super intelligence will turn us into a pet of some kind. Then the risk is we think we are controlling it while we are really the super intelligence's lap dog.

That is an argument that at least makes sense.

The super intelligence as homicidal maniac just doesn't make sense. There is less intelligent wildlife all around us and we mostly completely ignore it. We have more interesting things to do with our time as intelligent beings than carry out a bird or rabbit genocide.

It almost seems like the projection of some kind of paranoid delusion about change.
