In a cameras-everywhere culture, science fiction becomes reality

Science fiction writer David Brin calls it "a tsunami of lights" -- a future where tiny cameras are everywhere, lighting up everything we do, and even predicting what we'll do next. Unlike George Orwell's novel "1984," where only Big Brother controlled the cameras, in 2015, cheap, mobile technology has turned everyone into a watcher. A snowboarder with a GoPro can post a YouTube video of a friend's 540-degree McTwist in the halfpipe. But also -- as happened recently -- a Penn State fraternity can upload Facebook photos of partially naked, sleeping college women. A San Jose homeowner cowers behind a locked door while she watches an intruder stroll through her home on a surveillance video.
