About This Podcast

A podcast that explores the unseen and surprising connections between nearly everything, with special emphasis on intelligence and the search for Artificial General Intelligence (AGI) through the lens of Karl Popper's Theory of Knowledge. David Deutsch argued that Quantum Mechanics, Darwinian Evolution, Karl Popper's Theory of Knowledge, and Computational Theory (aka "The Four Strands") represent an early 'theory of everything' be it science, philosophy, computation, religion, politics, or art. So we explore everything. Support us on Patreon: https://www.patreon.com/brucenielson/membership
