Robert J. Sawyer, a Canadian science fiction author, gave a fascinating talk at Google’s Waterloo office. He discusses how the world wide web might gain consciousness, the subject of his latest trilogy. The talk touches on several topics related to theories of consciousness, and is worth watching.
I would also recommend picking up his latest novel, Wake, the first book in the WWW (Wake, Watch, Wonder) trilogy. I’ve read the book and the trilogy is off to a great start. I will definitely be picking up the other books when they come out.
