About Debatable:
https://itsdebatable.com/
Debatable is an AI-powered debate platform designed to sharpen human critical thinking, structure complex arguments, and challenge cognitive bias through real-time feedback and debate analytics.
The Big Question
AI can now construct logical arguments, challenge assumptions, summarize opposing views, and judge debates.
But if AI becomes better at arguing than we are, will humans become sharper thinkers—or simply stop thinking for themselves?
This is not a traditional lecture. It is a Live Debate & Cognition Experiment.
Choose Your Stance Upon RSVP
When you register, choose the position you are willing to defend:
PRO-AI (AI Sharpens Thinking): AI serves as a cognitive sparring partner, exposing logical fallacies, expanding our horizon, and elevating human metacognition.
CON-AI (AI Atrophies Thinking): Outsourcing friction and argumentation to AI weakens human intellectual resilience, leading to cognitive laziness and algorithmic bias.
Debate Agenda (4:00 PM – 6:00 PM)
4:00 PM — Opening & Anonymous Pre-Vote
Everyone votes anonymously: Does interacting with AI improve or degrade your independent reasoning?
4:20 PM — Opening Statements & Frameworks
Henry Kendall & Aidan Hollinger-Miles set up the live experiments and cognitive frameworks powered by Debatable.
4:35 PM — 4 Rapid Battles (Audience + AI Co-Debate)
Battle 1 (Persuasion): Can AI understand an argument, or is it just predicting persuasive words?
Battle 2 (Judgement): Would you trust an AI judge to evaluate human logic without bias?
Battle 3 (Education): Should students use AI to construct thoughts, or protect AI-free cognitive spaces?
Battle 4 (Identity): If AI argues both sides better than you, what does it mean to have your own opinion?
5:25 PM — Cross-Examination & Audience Flip
Challenge either side. You are explicitly allowed to change your mind.
5:50 PM — Post-Vote & Comparison
We reveal the shift: BEFORE vs. AFTER. Did the debate actually change your mind?
Brain Food Question
If your AI can always argue both sides of any issue better than you can, what should your Second Brain remember about what you actually believe?

About Second Brain AI Salon
AI is becoming more capable every day, but one fundamental challenge remains: memory.
How can AI understand context, learn from experiences, and collaborate with humans over time?
The Second Brain AI Salon is a weekly gathering in San Francisco bringing together AI builders, founders, engineers, researchers, and thinkers for open conversations about the future of AI, memory, agents, and human-AI collaboration.
This 8-week conversation series explores how AI will evolve from powerful tools into intelligent collaborators.
Join the Conversation
Second Brain AI Salon is intentionally small and conversational.
We welcome founders, engineers, researchers, educators, designers, students, builders, and curious minds who are interested in where AI is heading — and what humans will become alongside it.
Come for the conversation.
Stay for the people, ideas, and unexpected connections.

Second Brain AI Salon
Exploring memory, intelligence, and human–AI collaboration — one conversation at a time.
AI is becoming more capable every day. But as AI becomes more intelligent, one fundamental question becomes increasingly important:
How can AI understand context, learn from experience, and collaborate with humans over time?
Second Brain AI Salon is a weekly gathering in San Francisco bringing together AI builders, founders, engineers, researchers, educators, and independent thinkers for open conversations about the future of AI memory, agents, intelligent systems, and human–AI collaboration.
Across eight Fridays, we are exploring a broader question:
How does AI evolve from a powerful tool into an intelligent collaborator?
Each week approaches this question from a different angle — from memory and education to agents, software creation, human–AI collaboration, and ultimately the communities and systems that will shape the next generation of Silicon Valley.

What does AI lose when it cannot remember? Exploring memory, context, continuity, and the foundations of the AI Second Brain.
Week 2 · August 7
Building the AI Second Brain & LingCode
How can AI become a persistent cognitive partner rather than a collection of disconnected conversations?
Week 3 · August 14
AI, Education & the Future of Intelligent Companions
