This is interesting, but it is a bit depressing. If even one quarter of this is true, you can see why people might find it difficult to establish a secure, reliable telecommunications system.

This is interesting. See  Martyna Marciniak  and  Semantic Closure . I found this talk whilst looking for Robert Rosen's posthumously published 1991 book Life Itself - A Comprehensive Enquiry into the Nature, Origin and Fabrication of Life . Here is a well-written review by Sarah Voss. See also Robert Rosen’s Relational Biology Theory and His Emphasis on Non-Algorithmic Approaches to Living Systems by Patricia A. Lane. It's quite sane, but I think I could help with the meta-dynamics of open systems ( 31:20 ) In short, the meta-dynamics of the open system is effectively the embodiment of the organisms' own cognitive system in its environment, so it's a shared interlocking and interdependent phase space. That is why I have so much trouble with the ideas of Levin and his followers who plug living tissue into a neural network and then select for certain behaviour they think will attract funding or attention or something, and it's invariably in very poor taste.

It's a really great discussion about the novel Trust by Hernan Diaz . It sounds good, but really complicated. I can imagine needing to write notes to be able to figure out what I'm supposed to be reading and if I was doing that I might as well be trying to explain quantum mechanics or something. However, this does remind me a bit of The Blazing World by Siri Hustvedt, which I really enjoyed. Apparently (though not to me, I only just read this in another review ) the title is a reference to Margaret Cavendish 's novel  The Description of a New World, Called The Blazing-World .

Great talk about open source and FSF politics.

That's not to say that rewriting  garbage in rust is a better thing to do! Don't write garbage!

This is really interesting. She explains how, through self-reference, she became the Pope. At least that's how I imagine López-Díaz and Gershenson would put it (see Semantic Closure ). See  Emanuele Tesauro's ' Il cannocchiale aristotelico ' : 15:33  What she is referring to by the phrase pre-optical notions of vision is, I think, ideas such as that of  Extramission , which seems to have been entertained by Euclid in his Optics ! I think the quote of Stanisław Lem she is referring to at  30:00 is this passage from Summa Technologiae , specifically the chapter Intelligence: An Accident or a Necessity? : When it comes to changes that would knock an organism out of its environmental equilibrium by “programming” some unforeseeable instincts into it, the answer of the “first-order regulator” turns out to be unsatisfactory—which results in a crisis. On one hand, the mortality of non-adapted organisms suddenly increases, while at the same time, selection pressure privileg...

See Closing the Loop: How Semantic Closure Enables Open-Ended Evolution?  by Amahury J. López-Díaz and Carlos Gershenson.   I found this sentence quite striking: "This manuscript explores the evolutionary emergence of semantic closure—the self-referential mechanism through which symbols actively construct and interpret their own functional contexts, ..." The paper has apparently been accepted for publication in the Royal Society's journal Interface . One wonders what these little symbols could be getting up to while mathematical biologists aren't paying attention, ... I suppose we should ask Steven Wolfram . See  Martin Elsman - Deriving a Kronecker-Free Functional Quantum Simulator . That talk Samson Abramsky gave in 2012 was really thought-provoking:   In particular A computable expression of closure to efficient causation by Matteo Mossio, Giuseppe Longo and John Stewart. The question about self-representation in total functional programming is an interestin...

See the paper Deriving a Kronecker-Free Functional Quantum Simulator .    17:22  How hard it is to find comprehensible surveys in this field. Reply by Samson Abramsky.   There was also a talk by Martin at ICFP 2026 ( 7:41:22 ) but they forgot to charge the microphone or something. However it's audible from 7:55:13 . Samson Abramsky on Quantum Monads 8:00  On relations and graph isomorphisms: the Heisenberg-Weyl algebra is a special case of generic graph rewriting.  See The algebras of graph rewriting by Nicolas Behr, Vincent Danos, Ilias Garnier and Tobias Heindel. I wonder how much proof theory can fit into this framework of isomorphism classes of graph-rewriting systems. See for example Sequent calculi for a unity of logic by Norihiro Yamada..: "Classical logic is the logic that permits unrestricted premise consumptions and reasoning do-overs , and is unaware of either".  See  The Sheaf-Theoretic Structure Of Non-Locality and Contextuality ...
