15 years ago these types of systems were very concerning even though they were to "stop terrorism." If they're just being used for drug dealers now... give me a break.
It's drug dealers now. It's not difficult to see states using this to target women who travel for abortions, people traveling to political events etc.
Mark my words, it will be even worse: our "social score" will be affected by our behavior and travel patterns, following rules that nobody, even their creators, know or understand. "Something that you're doing on every day basis is linked to people who do harm to society, here's your -0.1 scp/day".
It's already being used to target women who travel for abortions. We're already there!
