We will watch and discuss the video http://mitworld.mit.e... which is a debate held November 2006 at MIT between Ray Kurzweil and David Gelernter moderated by Rodney Brooks. It's an excellent video that touches on many of the key issues of the field. We'll pause after each speaker has had their turn to reflect on what they said. Feel free to watch the video ahead of time so that you can prepare for our own lively discussion, which (as usual) I expect to continue for the full two hours of our meeting.
