Ep 263: David Deutsch's "The Fabric of Reality" Chapter 13 "The Four Strands" Part 4 - and final.

Today CEO of the world's most valuable company, Nvidia, Jensen Huang, announced "AGI has arrived". https://x.com/JensenHuang/status/2096700264569090384?s=20 Some reflections on all that.

This is in response to episode 489 of Sam Harris' "Making Sense" podcast - in a section only available via subscription. I have clipped the approximately 60 seconds worth of material I am narrowly responding to for fair use in this commentary. The case unpacked is, roughly, that morality can be disconnected from (is orthogonal to) reason broadly is no more than a restatement of moral relativism - and hence false. Morality and science are about objective reality so cannot be “orthogonal”. Moral progress goes hand-in-hand with reason broadly and any “sufficiently advanced” intelligent system would not only realise this, they must understand it to make unbounded, rapid progress.

A analysis in Popperian style of Candace Owens' "mode" of debate and discussion, approach to evidence and thinking and a comparison to the more mainstream evaluations of this debate.

All about the distant future. What does cosmology tell us about the fate of the universe, life and intelligence in some ultimate sense? Frank Tipler's The Omega Point Theory is the primary focus, but throughout we consider the centrality of The Turing Principle for predictions about the future of the cosmos, Roger Penrose's "Conformal Cyclic Cosmology" and some of Freeman Dyson's ideas.

What do our best explanations tell us about the ultimate ends of the universe? What is the difference between forming a world view about any one of the four strands (evolution, epistemology, quantum physics or computation) versus taking all four of them seriously?

How do the Four Strands of the Fabric of Reality - Quantum Physics, Computation, Epistemology and Evolution by Natural Selection hold together? What does taking them each seriously and all of them together seriously? Is it possible to construct a worldview without one of them or based on a single one alone? What do they imply about free will and consciousness? Doesn't making progress require us to assume them false? All this and more.

This episode is heavily focussed on Dawkin's "Selfish Gene" explanation of Darwin's evolution by natural selection. Obviously there are readings from the relevant part of this chapter from The Fabric of Reality but I augment that with sections from "The Selfish Gene" itself as well as "The Beginning of Infinity" as well as a larger portion of me providing additional unpacking and exposition.

Do not destroy the means of error correction. A deep unification of knowledge akin to unifying quantum theory with computation to create the theory of quantum computation. David Deutsch will be known for not merely forging the basis of quantum computing but also a new basis for morality and epistemology. I explain much of that here. "What should we do next?" is a question with an answer that is right or wrong, good or evil, better or worse. All existing moral frameworks philosophers debate are theories that can serve as criticisms of "what to do next". Morality is as objective as domain as mathematics, physics or anything else. Relativism, like it's sister philosophy dogmatism is false.

Response to a question about my discussion with  @drpeterboghossian  here: https://youtu.be/72vhtT0pFmA?si=hAx1kPho4DkLkBFN This is yet another way of coming at a critique around the concept of "belief" or those who profess to "believe" and so on using Deutsch's approach that knowledge is "information with causal power". I explore that for around the first 40 mins. If you're in a hurry, skip to the final 15 or 20 minutes where I get to responding to the meat of the matter in the question itself.

In this, the third and final part of a series, I break down some work Michael Levin has done with sorting algorithms. That seems very dry until you hear his claim that these algorithms that are well known and have been studied for decades exhibit extremely unusual behaviour never before spotted because "no one ever bothered to look". This part of the interview is between Ferris and Levin is referring to this paper: https://journals.sagepub.com/doi/10.1177/10597123241269740 which is available on the arXiv at https://arxiv.org/pdf/2401.05375 and which a Forbes writer authored this "explainer" of sorts here: https://www.forbes.com/sites/andreamorris/2025/11/13/the-secret-life-of-algorithms/ and which Levin himself explains here: https://thoughtforms.life/algorithms-redux-finding-unexpected-properties-in-truly-minimal-systems/ Michael Levin has done some very interesting work in biology around worms regrowing heads and so on. But this "research" is quite a departure from that.
