Thread 01 History of computing
A computer can carry our words. Could it also help us think thoughts we could not think before?
Follow one strand of computing’s history: the dream of connecting knowledge, extending the mind, and making new kinds of understanding possible.
011930s–1940s
What if knowledge could become a shared human inheritance?
Before the personal computer, there was a much larger dream. H. G. Wells imagined a continually renewed world encyclopaedia: knowledge organised for everyone. Pierre Teilhard de Chardin described a noosphere, a planetary sphere of thought emerging from human life.
Wells offered a programme for education; Teilhard placed collective thought inside an evolutionary and theological vision. Reading them together opens the question that runs through this thread: what might people become capable of when their knowledge is connected?
Cartographer of Futures
A novelist who used imagined worlds to question his own. Beyond time machines and invaders, he dreamed of knowledge held in common.
Thinker of the Noosphere
A Jesuit and palaeontologist who looked at human thought on a planetary scale. His noosphere placed minds within a larger story of life.

How could a machine help us follow the associations in a mind?
Vannevar Bush’s memex was an imagined desk for reading, annotating and joining records into trails. The interesting unit was the connection: one thought leading to another, a path another reader could follow and extend.
The World Brain asks how knowledge might be gathered. The memex brings the question to a person at a desk. A collection becomes useful when someone can find a way through it.
031937–1948
What can a message become when it is expressed in bits?
Claude Shannon connected Boolean logic to switching circuits, then gave communication a mathematical framework. His 1948 paper considered how messages could be encoded and recovered through channels, including noisy ones.
This is a foundation for carrying information, rather than a measure of its meaning. The distinction matters: transmitting a library and understanding it are different achievements. The next question belongs to the people using the machine.
041962–1968
What if the computer helped a group become better at thinking?
Douglas Engelbart approached computing as a way to improve human problem-solving. His 1962 framework joined tools with language, methods and training. Changing the machine was one part of changing how people could work together.
In 1968, Engelbart and his collaborators demonstrated NLS: text could be edited, linked and navigated while people worked across a shared system. The mouse was an instrument inside a larger ambition—improving our capacity to tackle difficult problems.
051960s–1980s
What could a child think with a medium they could change?
Seymour Papert made programming a material for learning. With Logo, children could give a turtle instructions, see what happened, and revise their ideas. Cynthia Solomon and Wally Feurzeig belong in the story of the language’s development.
Alan Kay’s Dynabook imagined a personal medium for reading, drawing, simulating and composing. His work with the Learning Research Group at Xerox PARC helped turn that ambition into Smalltalk and interactive environments. Both invite the learner to become an author.
Maker of Powerful Ideas
A mathematician who put children in command of the computer. Turtles, programs and things made by hand became ways to think about thinking.
Inventor of Dynamic Media
A computer scientist who imagined a personal medium for children of all ages. A place to read, draw, model and make ideas come alive.
061984–1987
What changes when everyone can make their own tools?
Bill Atkinson gave creative ambitions a practical surface. QuickDraw made the Macintosh’s graphics possible; MacPaint invited people to draw. HyperCard went further, letting readers become authors of interactive stacks containing pictures, text, buttons and links.
With Dan Winkler’s HyperTalk, those stacks could respond to their users. Atkinson belongs here as a bridge from the personal medium imagined by Kay to the question that still animates tools for thought: how much of our computing environment can we make for ourselves?
072012–present
Which parts of the dream are still waiting to be made?
Bret Victor’s essays and demonstrations ask for representations people can see, manipulate and understand. His work with Dynamicland carries that investigation into a shared physical environment.
Andy Matuschak explores how a medium can help people understand, remember and use what they read. With Michael Nielsen, he made Quantum Country and argued for renewed experiments in tools for thought. These are invitations to participate in an unfinished inquiry. A reader can become a maker.
Maker of Visible Thought
A designer pursuing media that help people understand what they create. His demonstrations turn hidden processes into things we can see and explore.
Cultivator of Understanding
A researcher asking what might come after the book. His work explores media that help ideas become something a reader can remember and use.
