Rationality, Ideas and Connection: ACX Meetup Luxembourg | Special Edition #23

This is a special collaboration session with the Astral Codex Ten Community, Responding to the call for Meetups Everywhere 2025 we are orgnizing as the Luxembourg Chapter. Since its a niche community, we decided, why not just introduce what is this "Astral Codex Ten (ACX)" about, and why do people around the world gather under its name?
