Vladimir Voevodsky's IAS lecture starts from Godel's second incompleteness theorem to explore whether first-order arithmetic could be inconsistent. It motivates his vision of univalent foundations and computer-checked proofs.

Markus Triska tours Prolog's most distinctive features, including its use as a database and query language, rule processing, constraint solving and compile-time rewriting. It also covers concise meta-interpreters.

A Clojure/conj 2016 talk demoing Barliman, a prototype smart editor that does program synthesis. Given a partial program and tests, it completes the program using a relational interpreter written in miniKanren.

Peter Thiel is the first guest on Eric Weinstein's The Portal, in a nearly three-hour conversation about technological stagnation, institutional failure and the link between growth and violence. They discuss universities, the economy and the search for a more ambitious future.

A 2012 Fortune dinner debate between Peter Thiel and Eric Schmidt over whether technological progress is healthy or stalling and whether Google can still innovate.

Arthur Keller gives a roughly half-hour crash course on environmental collapse, covering exponential growth, carrying capacity and ecological overshoot.

The 1972 documentary based on Alvin Toffler's book Future Shock, narrated by Orson Welles. It is a dystopian look at the accelerating pace of technological change and its psychological toll.

Tyler Cowen interviews Peter Thiel about technological stagnation, innovation, and lessons from Zero to One. The conversation ranges over business, startups and how Thiel thinks about progress.

Ross Douthat interviews Peter Thiel about technological stagnation, AI, longevity, space travel and politics. Thiel also lays out his framing of the Antichrist as a risk of civilizational stagnation.

A 1985 interview by G. Edward Griffin with former KGB operative Yuri Bezmenov. He describes long-running Soviet efforts at ideological subversion and manipulation of US public opinion.

A 1984 interview with former KGB agent Yuri Bezmenov on ideological subversion and psychological warfare, reposted in 2020 with a modern political framing.

A DevGAMM talk by Jonathan Blow arguing that civilizations can lose technological capability and that software quality is already deteriorating. He discusses how knowledge fails to transfer between generations.

A 2012 Harvard Institute of Politics conversation between Peter Thiel and historian Niall Ferguson. Thiel discusses technology, politics and his stagnation hypothesis.

Microsoft's Brian Beckman gives an hour-long, whiteboard-style walk through monads, building from function composition and monoids using school-level math. It is aimed at practicing programmers rather than category theorists.

Meredith Patterson and Sergey Bratus argue that networked software stays insecure because protocols and inputs are too complex to recognize safely. They propose using formal language theory and grammars to build secure, verifiable input handling.

Ben Eater explains how VGA signals work and builds a breadboard circuit that produces correct sync timing so a monitor recognizes the signal. He then builds toward displaying an image from simple logic chips.

Vsauce's roughly 24 minute explainer on the Banach-Tarski paradox, building from infinity and set theory to the decomposition of a sphere into pieces that form two spheres.

Mathematician Kevin Buzzard explains why he believes the Lean theorem prover will shape the future of mathematics, and describes digitizing his university curriculum in Lean with undergraduates, plus the cultural challenges.

Technology Connections takes a long, detailed look at how a 1970s electromechanical pinball machine works, from relays to stepper motors and mechanical logic. It is the first part of a series.

Leslie Lamport argues that programmers, like architects, should write rigorous specifications before coding, especially for concurrent and distributed systems. The talk introduces the case for writing specs (the TLA+ mindset) as a way of thinking above the code.

Vsauce's Michael Stevens takes viewers past infinity using transfinite numbers, ordinals and cardinals, with input from mathematician Hugh Woodin. It is a fast-paced, mind-bending tour of different sizes of infinity.

Jay Parlar's Strange Loop talk shows how model checkers such as Alloy can find complex bugs in a system's design without running or reading any code. He walks through modeling architectures and checking every possible sequence of operations, including a real security bug and a UI feature-interaction bug.

Edwin Brady, creator of Idris, presents Idris 2 and demonstrates type-driven development, where the compiler assists by filling holes and suggesting implementations from types.

Numberphile's James Grime explains Cantor's result that some infinities are bigger than others, including why the reals outnumber the integers. It is a short, accessible introduction to countable and uncountable infinity.

Guy Steele's PPoPP 2017 keynote surveying the history of computer science metanotation, including BNF, inference rules, and overline notation. He argues the field's notations are inconsistent and fragmented.

Edwin Brady presents Idris 2, a rewrite of the Idris dependently typed language, and shows type-driven development in practice. The demos show the compiler filling in whole functions from their types.
