Thank you for your comment @juanmolina. I really appreciate that.

I think we have here a clear relationship with the controversial facial recognition systems that are intended to be installed in commercial establishments and streets in certain cities.

Definitely. Did you know that some of these systems can even recognize human by the "style" of walking?

The problem is not the technology itself, the problem is man.

That's generally crucial point. AI itself can't be good or bad (Terminator vision is really unlikely). It's rather all about what humans do with this technology.
