Living Brain is an invitation-only evening by OpenAI x ChatAndBuild, creators of ChatChat, focused on exceptional humans and the quiet technologies that help them go further. The event explores a more human role for technology—not as the hero, but as a companion—through real stories of endurance, reinvention, discipline, and survival. The evening brings together athletes, survivors, builders, creators, founders, technologists, and leaders for a story-led experience centered on human potential. Speakers include 2x Guinness World Record Holder Natalie Dau and Al Qaeda hostage survivor Stephen McGown. The event concludes with a ChatChat experience demonstrating how wisdom from these stories can continue through AI agents that guests can engage with after the event.
