I think the stasi world was actually more terrifying than an AI eye in the sky.
Because you couldn't trust anyone, not your friends or family. Everyone was part of a big network out to get you, so you were sort of locked in your own head.
The more realistic fear for me is ending up in a cyberpunk dystopia where the world is run by 3-4 big corporations. Which is ofc not something they like to bring up.
