The opening episode of Ted Nelson's Computers for Cynics series, in which he casts doubt on conventional accounts of computer basics. He argues that conventions and packaging are mistaken for technology.

A 1979 CBC radio interview in which Ted Nelson tries to explain how computers could serve as tools for thinking and visualizing. The interviewer keeps failing to grasp the idea, and Nelson patiently answers again and again.

Uber Engineering's Joseph Gilley explains why Uber uses hexagons for geospatial indexing and introduces H3, its open source hierarchical grid system. He covers use cases and how distortion is handled.

A full upload of Alan Kay's 1987 talk, with demos of several Smalltalk-era software systems and ideas about visual, kinesthetic and symbolic reasoning. It includes a Smalltalk program written by a 12-year-old and footage of the Rand tablet.

Alan Kay's 2015 talk on the power of simplicity, arguing that systems become simpler by building on more sophisticated fundamental building blocks and that big research horizons drove invention at Xerox PARC. It ranges across computing, tools and scaling software.

Dan Olson of Folding Ideas spends months in the virtual world Decentraland and delivers a long critique of the metaverse, NFTs and DAOs, and why virtual worlds fail as places.

Johnny Lee demonstrates head tracking with a Wii remote and a head-mounted pair of IR LEDs, so a screen acts like a window into a 3D scene as your head moves.

Mike of mikeselectricstuff shows his heavily modified old BBC Micro system in a 28-minute tour of 8-bit hardware archaeology.

Alan Kay visits Carnegie Mellon's School of Computer Science in 2007 for an informal conversation with faculty and students. He discusses the state of CS education and criticizes mainstream computing.

John Carmack speaks at UMKC's 2017 commencement event about the difficulties of VR, especially end-to-end latency across hardware and software. He covers why latency and buffering matter and how nausea is addressed.

Lex Fridman interviews chip architect Jim Keller about the future of computing, AI, life and consciousness. Topics include CPU design, branch prediction and why imperfect designs often win.

PBS Infinite Series explains how Shor's algorithm lets a quantum computer break RSA encryption, building on earlier episodes about cryptography and the math of quantum computers. It works through the idea step by step.

Dave Ackley presents robust-first computing and the ULAM programming language for the Movable Feast Machine, a cellular-automata-like architecture. It was a short video for the Future Programming Workshop 2015.

A demonstration of SymbOS, a multitasking operating system for 8-bit Z80 machines, running on a real MSX turboR with an MP3MSX card and a CF IDE interface. It shows the OS playing audio and running a graphical desktop on very old hardware, captured from the real machine and not an emulator.

Tom Scott visits the Swiss Military Museum to see the last surviving 1970s tank-driving simulator. It uses a real camera moving over a miniature model landscape rather than any computer graphics.

Keiichi Matsuda's short concept film depicting a future where physical and virtual realities have merged and the city is saturated with media and advertising. It shows an augmented-reality-filled daily life as a provocative vision.

An Asianometry explainer on why the Soviet Union, once a leading computing power, fell far behind the US in computers by the 1980s. It traces the gap from the 1960s onward despite strong state support for science.
