I think we're in both a time and among an audience (HN readers) where privacy/surveillance issues tend to drive the conversation. I don't think that's bad, but I agree that it's a little disappointing that the main reaction among the HN crowd to the promise of ubiquitous computing is to immediately focus on all the ways it can be used for evil.
My own take, which is either naive or mercilessly pragmatic depending on how you look at it, is that it's going to be a lot more productive to start thinking about how to protect privacy -- and, bluntly, what tradeoffs we're comfortable making as a society, which may not mean "share nothing unless explicitly told otherwise" -- in an always-on, always-connected world where networking will almost certainly become so pervasive that we largely stop even thinking about "the network."
