"The Web Is a Human Meta-Brain": Tim Berners-Lee Could Have Been a Billionaire If He Had Sold His Invention, the World Wide Web. Instead, He Is Campaigning for Internet Access to Be a Fundamental Right of Everyone on Earth

Article excerpt

Twenty years ago, Tim Berners-Lee launched the World Wide Web among a small circle of fellow computer enthusiasts. Today, the 56-year-old Briton remains one of the internet's most vigorous advocates. Its vast success, however, has had a downside: it has exposed him to a bombardment of requests from visionaries, obsessives and rubberneckers, as well as hordes of children demanding help with school projects. All expect him to exist as some kind of open-source human being.

Berners-Lee has never been an enthusiastic self-publicist. Nowadays, he shelters behind carapaces of email gateways and protective staff. He seldom gives interviews. If you're not persistent and pertinent, you may not even earn a rebuff. "I'm quite busy," he explains - a huge understatement - when eventually we talk on the phone.

"I have built a moat around myself, along with ways over that moat so that people can ask questions. What I do has to be a function of what I can do, not a function of what people ask me to do." (He tends to use techy terms such as "function" quite a lot. He doesn't mind "geek", either.)

That the creator of the web - a father of two children, separated from his wife and based in Cambridge, Massachusetts, where he pursues his research at the Massachusetts Institute of Technology - has to live like an electronic Howard Hughes is just one of the many paradoxes that his invention has thrown up over the past two decades.

Nevertheless, Berners-Lee is campaigning for ever more openness, pushing for the internet to exist as a free-for-all, unfettered by creeping government interference or commercial intrigue. He believes that access to the internet should be a human right.

Born to mathematician parents in west London in June 1955, Berners-Lee studied at Oxford University, graduating with a First in physics in 1976. In 1980, he joined the European Organisation for Nuclear Research in Geneva, better known as Cern, as a consultant but left a year later to become director of the tech firm Image Computer Systems.

Returning to Cern in 1984, he started working on hypertext to help researchers share information. His new project could easily have been dismissed as another case of a back-room enthusiast tinkering with clunky, electronic networks: even though he had the ability to construct a computer using a soldering iron and an old television set, Berners-Lee was just one of many sandal-wearing scientists.

"I wanted to build a creative space, something like a sandpit where everyone could play together," he says now. "Life was very simple. I was too busy to think about the bigger questions. I was writing specs for the web, writing the code. My priority was getting more people to use it, looking for communities who might adopt it. I just wanted the thing to take off."

Berners-Lee formally introduced his hobby-built system to the world on 6 August 1991 by posting a message on an internet bulletin board for fellow hypertext program developers. That day, he put the world's first proper website online. It explained what a website was and gave details of how to create one. Neither initiative caused any immediate interest.

It feels odd to picture him struggling to convince people of the web's potential. "It was just a load of hard work," he says - "getting up in the morning and thinking, 'What the hell will I do today? Should I ask people at Cern to instal browsers? Should I get more servers running, write more code for browsers, or should I talk at a conference? Or should I do my own website as an example for other people?'"

At the time, computer fans were an obscure minority, their efforts loudly derided by analogue hipsters. Steadily, however, the World Wide Web gained momentum as the limited group of early users - computer scientists and military and government agencies - expanded until it attracted a critical mass in the mid-1990s. Now, according to the analyst Internet World Stats, over 30 per cent of the global population - more than two billion people - have online access. …
