That sounds quite optimistic. How do you "define exactly [...] where, and when" you can have privacy when you don't know where and when a camera or microphone might be aimed at you? Anthony Bourdain's photo, referenced in the article, was presumably taken by a friend or family member only to be leaked a decade later. And these days, using readily available tools such as telephoto lenses or unidirectional microphones, strangers can take part in your life from a distance of hundreds of feet. So, do you "define" privacy by making sure there never is a hill in line of sight? When people start live-tweeting events recorded by their private satellite at some point in the future, do you make sure you can't see the sky so that the sky can't see you? That's not the kind of privacy I'm looking forward to, and it's certainly not a boon. EDIT: You are certainly correct that this will force us to define what privacy is -- or, more likely, to dismiss the concept altogether. Either way, it looks like we'll have to embrace this fundamental change, I can see little point in trying to fight against it.
