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 ...

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 ge...

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...

Comparing Kuhn and Popper on Quantum Theory: Here we go deeper into the differences between Karl Popper and Thomas Kuhn's account of how science moves from one theory to another. David applies the theory set out in part 1 of this chapter to the specific case of quantum theory. Did social forces have a major impact on whether quantum theory was adopted as Kuhn would have it, or were rational factors like argument and experiment cruc...

This is effectively part 3 in a series of responses to the Prime Minister of Australia about censorship, legislation, policy, philosophy, Bondi and Social Media. The Prime Minister attempted to explain, as best he could, the reasons for banning under-16 year olds from certain social media platforms. I remark on an interview he conducted and make some broader remarks in conclusion to a short series on his response to the Bondi trage...

This is a reproduction of a talk I gave to some trainee surgeons in Sydney who, among other things, were learning about AI as it was affecting their own field. It is, in a sense, a summary of many of the points I have been making recently on this channel with respect to AI and pessimism around it.

We are told by people working in the field, researchers and those who publish academic papers on the topic that artificial intelligence or deep learning or LLMs or Machine Learning or Recurrent Neural Networks - call them what you like - employ some form of inductive reasoning.
