Er... they're suggesting that we brand sociopaths and basically ends it at that. I'll pass on a world where having a bad day could lead to enforced disfigurement.
Fair, but this sort of scenario wouldn't exactly exist in isolation right? Would a society that is willing to physically brand people with a permanent "STAY AWAY" marker be super tight in their regulation of diagnosis? lol. This conversation is insane.
There will be privacy until the singularity, don't worry.
Continued encroachments on privacy and personal autonomy may indeed deteriorate them, even cripple our ability to protect those rights, but simply worrying about that doesn't mean I must go gentle into that good night.
