Indeed, it's all a combination of assumption and observation. And of course, technical knowledge.

I could go into deeper details of the whole context but it is very difficult in this form.

But for this dialog I think the most important aspect, which we also agree on, is that we can assume a huge number of people to be 'broken' or in need of help, which is the attack vector I was referring to.

And in that context, I am convinced the tech bros have absolutely no idea what they're doing (to humanity).
