I'm on the fence. Social stuff is good, but I worry that a lot of the potential topics are things I won't have anything to contribute to (e.g. AI-related things I have no background in) or be able to keep up with. I invite people to try to nudge me to one side or the other.
Don't assume we spend all our time talking about the deep, ultimate truths of the universe. Last time, we spend far more time talking about our lives and social rationality than (in the one example I remember occurring) the computability of the universe. If you want to socialize, there's no real pressure to be thinking "DEEP THOUGHTS". People (around here) tend to be biased against changing their routines and trying new things, so you should try to correct in the other direction. I promise you will enjoy yourself.
Last month, about 7 people showed up to the Berkeley LW meet-up. To build on that success, we will be meeting on Saturday, October 9 at 7 PM at the Starbucks at 2224 Shattuck Avenue. I'll be there with a sign saying "If you read Harry Potter and the Methods of Rationality, come talk to me." Last time, we chatted at the Starbucks for about an hour then went somewhere for dinner, so don't feel like you have to eat before you come. Hope to see you there!
