What would it take to make these things absolutely terrifying?
Bonus questions.. Would you listen to a bucket of electronics if it starts ordering you around? And what if you resist? What do you think the capabilities of these things will be in say 10 20 50 a hundred years into the future?
Well, on the positive side, the world would continue it's march into a complete lack of nuance.
Oh...wait...that's not positive.
Ultimately it will depend on how they are used, etc.
In some ways, we already do use electronic 'cops' for some things.
We have speed cameras, and red light cameras, both of which are kinda positive if used in the right manner.
We also have things like automated fraud detection on credit cards which is much more effective than humans in detecting possible white collar crime, and protecting people from it.
But the idea of a Robocop is a little scary, I have to admit. I would assume they'd make them colour-blind, though, so there is that.
