Ep 273: Super Intelligence: Then and Now. Fiction and Reality. Part 2
Comparing ideas around "superintelligence" over the last decade. How have visions of what "SI" or "AI" or "ASI" and AGI evolved since Bostrom wrote "Superintelligence". This is the combination of various recent YouTube videos but counts as a sequel to part 1 found here: https://www.youtube.com/watch?v=dZ5OyhZ70wA or back at Episode 271 of the podcast.

Ep 272: Is science truly explanatory?
A reaction to @CosmicSkeptic and @SabineHossenfelder discussing the nature, or even possibility of, genuine scientific explanation in this video: https://youtu.be/KWBm0_1QBDs?si=3JwIDGAtumO3mfBz Which of them is correct? Or are they both wrong? What counts as an explanation? What counts as a scientific explanation? What counts as a good scientific explanation? And is Alex right that science, in some ultimate sense, really only ever describes things?

Ep 271: Super Intelligence: Then and Now. Fiction and Reality. Part 1
This is Part 1 of 2 where I compare and contrast what philosophers were saying about the possibility of "Super Intelligence" many years ago with respect to the discourse today. What did Nick Bostrom say over a decade ago, and what is he saying today? How is the discourse being framed and what are the major commentators saying, in their own words?

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.

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.
