wo main threads are combining just now to change the way that we live in public space. Of course, as Steve Rambam says (reprising Scott McNealy), "Privacy is Dead: Get Over It." We're used to how we have less privacy driving with GPS or using a cell phone or finding out that businesses have compromised our personal information. Even The Onion Router (TOR) has lots of exit nodes captured, and RSA encryption is compromised. So good luck keeping our affairs private. 

Still, we're used to having urban anonymity. People we pass on the street don't necessarily know what we're up to or who we are by name. Neither do the businesses we pass or the police. This is probably going to change, though. When it changes, it will probably be big platforms that do it.
