I volunteer as Pause AI software team lead and confirm this is basically correct. Many members and origins in common between the global Pause AI movement and Pause AI US, but some different emphases mostly for good specialism reasons. The US org has Washington connections and more protests focussed on the AI labs themselves. We work closely.
Neither has more than a few paid employees and truly full-time volunteers. As per OP, anyone who agrees activism and public engagement remain a very under-leveraged value-add way to help AI safety has massive opportunity here for impact through time, skill or money.
I understand it went well.
Where can we find recordings of presentations and other outputs? Not yet seeing anything on https://www.aisafety.camp or in the MAISU Google doc homepage.
