This podcast explores the concept of reality as a delayed and processed construct of the brain, rather than a live experience. It delves into how the brain predicts and adjusts our perception, creating a "mental simulation" that runs ahead of raw data. The podcast further discusses how our sense of free will might be an illusion, with brain activity preceding conscious decisions. It touches on the double-slit experiment in quantum mechanics, suggesting that observation influences reality, and introduces the idea that our senses provide a user interface, not an accurate representation of the world. The podcast concludes by questioning the nature of reality and our role in shaping it.
