Did you miss the September 29 lecture? You can now catch the event on YouTube. The three sections of the talk are in individual videos, so you may skip directly to the portion which interests you. The audience interactions are at the end of the third section. Although the audio is fairly muffled due to the location of the microphone at the live event, there were a number of good questions asked, and many others were not picked up on the audio at all. Thank you all for your insight and curiosity!
