It's the last day of TEDGlobal 2013, which means goodbyes and premature reminiscing. Onward: In session 11, "Tech Impact," we heard about the dangers and delights of our accelerated technological age. We're doomed! No we're not! Yes we are! And in session 12, "All Together Now," we held mental hands and were reminded that, in spite of it all, we're in this together.
