As with any technology, it strikes me that it's not the technology that's the problem, it's the uses to which people will put it. Where is the line between open communication and data harvesting? When does the technology cross over from transmitting what you want to communicate to what you don't want to communicate (and who controls when it steps over).
Unfortunately, looking around at what people do with the technology we currently have in the seemingly endless quest to monetise every aspect of life, I feel cynical, and yet at the same time I'm aware that even with the problems of privacy we have these days, these are a categorical difference from starvation, rampant ill-health and the like that were the problems of earlier times.
