Bruce Schneier advocates for a technological “pause” to allow policy to catch up:
[U]biquitous surveillance will drastically change our relationship to society. We’ve never lived in this sort of world, even those of us who have lived through previous totalitarian regimes. The effects will be felt in many different areas. False positives — when the surveillance system gets it wrong — will lead to harassment and worse. Discrimination will become automated. Those who fall outside norms will be marginalized. And most importantly, the inability to live anonymously will have an enormous chilling effect on speech and behavior, which in turn will hobble society’s ability to experiment and change.Computers and Video Surveillance
On the other hand, isn’t it a good thing we can spot police officers with militant, racist views?
