The NotYASS session on the Matrix was interesting. A lot of people (or, rather, more than usual) showed up, including a lot of philosophers (from RSSS and the Department of Philosophy I suppose). There wasn’t much more than the various points, arguments and objections raised in the various papers at www.simulation-argument.com, but the discussion was interesting.
I’ll be missing the next session (I think it’s been cancelled anyway due to a conference or some such), but there are a few more philosophical topics scheduled for the next few session after that. They should be interesting if nothing else.
