,1,Donald Hoffman interview on spacetime, consciousness, and how biological fitness conceals reality. We discuss Nima Arkani-Hamed's Amplituhedron, decorated permutations, evolution, and the unlimited intelligence.
The Amplituhedron is a static, monolithic, geometric object with many dimensions. Its volume codes for amplitudes of particle interactions & its structure codes for locality and unitarity. Decorated permutations are the deepest core from which the Amplituhedron gets its structure. There are no dynamics, they are monoliths as in 2001: A Space Odyssey.
Background
0:00 Highlights
6:55 The specific limits of evolution by natural selection
10:50 Don's born in a San Antonio Army hospital in 1955 (and his parents' background)
14:44 As a teenager big question he wanted answered, "Are we just machines?"
17:23 Don's early work as a vision researcher; visual systems construct
20:43 Carlos's 3-part series on Fitness-Beats-Truth Theorem
Fitness-Beats-Truth Theorem
22:29 Clarifications on FBT: Game theory simulations & math proofs
24:20 What does he mean I can't see reality? Fitness payoff functions don't know about the truth...
28:23 Evolution shapes sensory systems to guide adaptive behavior... consider the virtual reality headset
32:45 FBT doesn't include costs for extra bits of information processing
34:40 Joscha Bach's "There are no colors in the universe"... though even light itself isn't fundamental!
36:36 Map-territory relationship
40:27 Infinite regress, Godel's Incompleteness Theorem
42:27 Erik Hoel's causal emergence theory
45:40 Don's take on causality: there are no causal powers within spacetime
What's Beyond Spacetime?
50:50 Nima Arkani-Hamed's Amplituhedron
53:00 What percentage of physicists would agree spacetime is doomed?
56:00 Amplituhedron a static, monolithic, geometric object with many dimensions...
59:23 Ties to holographic principle, Ads-CFT correspondence
1:03:13 Quantum error correction
1:05:23 James Gates' adinkra animations linking electromagnetism & electron-like objects
The Unlimited Intelligence
1:08:30 Does Don still meditate 3 hours every day?
1:11:30 "We're here for the ride..."
1:12:27 All my theories are trivial, there's an unlimited intelligence that transcends
1:14:00 Carlos meanders on meditation
1:15:50 "You can't know the truth, but you can be the truth"
1:17:43 Explore-Exploit Tradeoff (foraging strategy)
1:19:15 "You're absolutely knocking on the right doors here"... our 4D spacetime for some reason essential for consciousness
1:21:10 Why this world, with these symbols, this interface?
1:22:20 "My guess, one of the cheaper headsets"
Conscious Realism
1:24:40 Precise, mathematical model of consciousness... the end of Cantor's infinities
1:28:30 Fusions of Consciousness paper... bridges between interactions of conscious agents/Markovian dynamics → decorated permutations → the Amplituhedron → spacetime
1:35:20 In a meta way, did Don choose the highest fitness path for his career?
1:39:10 "Don't believe my theory, not the final word"
1:41:00 Where to find more of Don's work
