It is kind of a spooky concept from an Orwellian perspective.....even if it makes sense in the context of Hal being a space cop, but imagine.....
If the rings surveillance technology could be duplicated and used by employers or governments. People having to wear these rings at work, so that Jeff Bezos can make sure everyone is continually working and not talking about forming a union.
This is all conjecture of course, but I wonder how Hal (or other earth GL's) feel about the growth of security cameras all over street corners? They would probably like it, Ollie always had a better grasp of the political dangers of authoritarianism.
