Oh I agree with you there, it's at the same time terrifying as fascinating!

The premise that you just mentioned since they're very emotionless and we risk extermination if they fail to see a use for humans.. That also raises the question about their own existence, maybe they will fail to see the point of their own existence since they're not afraid to die and have nothing to live for.. But in short, I think no one knows what such levels of intelligence would act.

The risk is there for sure.

Thank you for such a great comment!
