I am not arguing about "bad things might happen".

I am specifically arguing hard against the concept that 100% of humans - or even 50% of humans could be killed by any mechanism at all. Humans would find it close to impossible. A computer program - come on.

This is the topic at hand - AI might wipe out humanity - it is being discussed all around the world by people who should know better - any it's the most fictionish of fictional fictions.
