The Meaning Code | How the Observer as Computational Entity intersects with Maxwell's Demon and the Demon Horde Sort @TheMeaningCode | Uploaded August 2022 | Updated October 2024, 2 hours ago.
Is the universe fundamentally computational? What is the observer? What is the role of the observer? A deep dive.

0:00. Intro
2:00 Analyzing 2 different delayed choice quantum eraser experiments:
Kim, et al and John Wheeler (Gedanken)
13:43 We never talk about what the observer is (we need to include the physics of the observer)
14:14 Maxwell's demon and the observer (a sequence of choices)
25:08 The Free Will Theorem
27:00 Multiple choices that are still consistent with the past history of the universe.
41:30 Observation does require a "concept" of consciousness.
49:25 Consciousness ends at the smallest composite systems capable of computation, those are the smallest units for which consciousness would apply. A sequence of choices based on a set of rules.
Must be causally disconnected from the universe as a whole in order to be an observer.
1:00:52 If you take computation as fundamental, you can get an ought from an is, which Sam Harris says is impossible to do.
1:08:15 Computation is always a physical system. If you take computation as fundamental, information is downstream or an artifact of that.
1:09:10 If you think in terms of computation, you immediately get languages.
1:20:55 A review of computation
1:21:34 Exposition of music as a computational system
1:31:08 Introducing Dave Ackley of the Demon Horde Sort
