Tim Berners-Lee

By Lucía Cárdenas

In March 1989, a software consultant at CERN, the European particle-physics laboratory outside Geneva, circulated a memo with the modest title 'Information Management: A Proposal.' Tim Berners-Lee, born in London in 1955 to parents who had both worked on one of Britain's first computers, the Ferranti Mark 1, was trying to solve a local problem: thousands of physicists, rotating through experiments, losing track of documents, data, and each other across incompatible computer systems. His proposal was a system of interlinked documents, and its genius was in what it did not require: no central authority, no permission, no single company. He defined three simple standards that together made the Web. The URL gave every document an address. HTTP gave computers a protocol for asking for documents. HTML gave documents a language for linking to each other. By Christmas 1990, working with Robert Cailliau, he had built the first web server, the first web browser, and the first web page, all running on a NeXT computer at CERN; the machine bore a handwritten label: 'This machine is a server. DO NOT POWER IT DOWN!!' The crucial decision came in 1993, when CERN released the Web's underlying technology into the public domain, royalty-free, forever. Berners-Lee could have patented it and become the richest man in history; instead he gave it away, and the Web exploded from a physics-lab tool into the universal medium of human civilization within a decade. He moved to MIT, founded the World Wide Web Consortium to keep the standards open, was knighted in 2004, and received the Turing Award in 2016. He now campaigns for a Web rebuilt on the open principles of his original design, warning that the centralized platforms that grew on top of it have betrayed its promise. The Web is young, barely three decades old, which is why its durability score is modest; but no invention since the printing press has reorganized human knowledge so completely. The first web page, running on that NeXT machine at CERN, explained what the World Wide Web was, a definition that now reads like a message from a simpler age. The early Web was text-only, navigated by a line-mode browser Berners-Lee wrote so it would run on any terminal; the graphical Mosaic browser, built by Marc Andreessen's team in Illinois in 1993, is what made it explode into popular consciousness. CERN's decision of April 30, 1993, to put the Web into the public domain was the hinge of the whole story: the laboratory's directors understood that a communications medium owned by no one would be adopted by everyone. Berners-Lee moved to MIT in 1994 and founded the World Wide Web Consortium, which has kept the core standards open and royalty-free ever since, a quiet act of governance without which the Web would have fragmented into corporate fiefdoms. He was knighted in 2004, won the Turing Award in 2016, and wrote 'Weaving the Web' to explain what he had intended. In recent years he has argued that the Web took a wrong turn into centralized platforms that harvest personal data, and he launched the Solid project to rebuild it around personal data pods controlled by individuals. Whether that campaign succeeds or not, the original act stands: the most valuable communications infrastructure in history was given away, on purpose, by its inventor.

Impact on civilization

The Web turned the internet from a tool for specialists into the nervous system of civilization. Because Berners-Lee made linking permissionless and addresses universal, anyone could publish and anyone could find: the result was the collapse of the gatekeepers of information, the rise of search, e-commerce, social media, streaming, remote work, and the entire digital economy, now measured in tens of trillions of dollars. His decision to give the technology away, rather than enclose it, is one of the great acts of economic generosity in history; a patented, tolled Web would have been a fiefdom, and the open Web became a commons. Every aspect of modern life, from how wars are reported to how teenagers flirt, runs on the three standards defined in a 1989 memo. The Web's openness is also the reason for its pathologies, and Berners-Lee has said so himself: permissionless publishing enabled both the sum of human knowledge and its pollution, both dissident movements and disinformation. That duality is the price of the design choice he made in 1989. No central authority means no central censor, and the civilization that got Wikipedia also got everything Wikipedia's editors spend their lives fighting. The experiment continues, and its inventor, unlike most, is still alive to argue about what it became.
