If you're interested in AI Safety I run 2-3 events a week out of Trajectory Labs.
(I guess I still run them even if you don't happen to be interested in AI safety.)
You can see our upcoming events here.
If you're interested in attending my non-work events you can join this Discord server or subscribe to this mailing list.
I am always open to hearing from people who have access to nice venues or good ideas for events they'd like my help hosting.
