This quick TED talk entry is courtesy of TED.com. In our digital world, social relations have become mediated by data. Without even realizing it, we’re barricading ourselves against strangeness — people and ideas that don’t fit the patterns of who we already know, what we already like and where we’ve already been. A call for technology to deliver us to what and who we need, even if it’s unfamiliar. (Filmed at TED@Intel.)
