As I stated in http://www.ai-meetup.org/calendar/12204303
Your homework for Sunday is to read the article at http://web.mit.edu/newsoffice/2009/ai-overview-1207.html
I strongly recommend that if you can, print it out so you can mark it up and bring it along. I will bring a couple copies for people without printer access but I won't have articles for everyone and since we're going to go through this paragraph by paragraph it will be difficult for you to follow the discussion if you don't have your copy with you. As we have wifi, you could also bring a laptop with a web browser.
And while you are reading, take copious notes of your thoughts, questions, and opinions so that we have something to discuss.
