Great!
I wouldn't be sure I count as a rationalist; I read everything on ACX (and have read SSC, including backlog), but I have stopped reading LW after not that long.
I have moved to Bordeaux a year ago (right after the move I wasn't able to commit in advance to being available on any specific day, so I didn't run a meetup last September), but during the spring Meetups Everywhere there was a person who showed up and has lived in Bordeaux longer than me, so I guess you two would have a chance to run your small ACX meetup a year or two ago…
I do indeed work on Peixotto campus (like the other person who was at the spring meetup — not sure if they will come this time).
This year's ACX Meetup everywhere in Talence (Bordeaux Metropole), Gironde, France.
Location: Parc Peixotto, middle of the path connecting the two main entrances (once we meet we'll seek which benches to try to grab). Initial position: https://www.openstreetmap.org/#map=19/44.80900/-0.58978 (Send me your phone if you expecte to be late and want an SMS when we deside which direction in the parc we shift) I will bring an A4 sign with «ACX Meetup» on it. I usually wear a mask in high-stranger-density settings. – https://plus.codes/8CPXRC56+H3W
Please RSVP on LessWrong so I know that someone is indeed coming. This will be a small meetup with no fixed topic, so whatever you want to discuss, we can discuss it!
