A link from AAAI alert to a radio show on IBMs Blue Brain project with Marvin Minsky, Brian Cantwell Smith, and Paul Davies. Talks about what a brain/consciousness is and gets into the ethics of various situations.
There's a link at this site to listen to the program. It requires RealAudio to listen.
