Ep 270: The Gradient Descent into Doom.
A spontaneous set of comments on the ongoing AI scare of 2026. What's happening in the media right now, on social media, in culture and at the highest levels of government. Why the pessimism and catastrophism? What can be done? Quite a few slides are referred to, but I do read through them. Incase you want the video - it's here: https://youtu.be/mItTFoYSCcA

Ep 267: The Orthogonality Thesis is Moral Relativism. (Response to Sam Harris on AI).
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.

Ep 265: David Deutsch's "The Fabric of Reality" Chapter 14 "The Ends of the Universe" Part 2 The Omega Point
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.

Ep 264: David Deutsch's "The Fabric of Reality" Chapter 14 "The Ends of the Universe" Part 1
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?

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