This video is a hard-hitting, chapter-by-chapter analysis that turns David Deutsch's The Beginning of Infinity ideas into a playbook: explanations with reach, error-correction as lifestyle, optimism with guardrails, universality as a design pattern, and responsibility you can audit. No fluff, just levers. If you build, teach, invest, legislate, research, or simply want your future to stop wobbling, this is your toolkit.

What you’ll get:
• A clean mental model for progress: conjecture → criticism → options → bigger conjectures
• How to test explanations so they stop being vibes and start moving reality
• Why abundant clean energy is the keystone and how to think about “unsustainable” as a design problem
• Decision hygiene that turns choices into compounding engines, with reversibility and kill-switch discipline
• Culture as knowledge-in-motion: institutions that protect dissent, metabolize failure, and scale learning
• Multiverse sanity, probabilities that behave, and ethics that survive branching futures
• How artificial creativity earns its seat: self-critique, interpretability, and safe reversibility

Use this to upgrade your teams, classrooms, labs, and policies. Steal the frameworks. Argue with them. Improve them. Then report back with receipts.
