The world wide web, the most disruptive technology since the development of steam power, the internal combustion engine and nuclear fission, has turned 25. It was born in March 1989 at CERN (now well-known for its dramatic pursuit of the Higgs boson) when Tim Berners-Lee, then a young researcher, proposed an architecture for the incremental storage and sharing of research data. It feels kind of weird to recall that just two and a half decades ago, we thought of information as stuff that sat still on paper, shopping as an activity limited to shops and spam as pink food out of a can. Meanwhile, a whole generation of the human race has grown up thinking that computers and smartphones make everything happen. Maybe that’s even weirder, in a world where the majority is still offline.
At age 25 or thereabouts, humans generally discover an answer to the eternal question: “Who am I?” The Web, however, exhibits an identity crisis at precisely that age. It has created millions of new jobs supported by hitherto impossible business models, like the online bookstore, but it has also wiped out traditional ways of making a living, like bookselling. From Tunisia to India, it has rekindled protest politics directed against authoritarian or unresponsive government. But after Edward Snowden’s damaging revelations, there is increasing disquiet about Big Brother snooping on private data. Ironically, there is as much disquiet in government, which is enraged to discover that it has been snooped on in return.
Consider the troll, who snuggles at the breast of social media. Or look at the paradox of Tor, the anonymising network developed with the honourable aims of bypassing censorship and protecting sensitive communications, such as those of journalists and activists working in hostile environments. It has sparked off a mini crime wave on the Dark Web, the part of the medium inaccessible to search engines and casual surfers, where drugs, guns, assassination contracts and child pornography enjoyed a flourishing market until a recent crackdown.
So, at 25, the Web does not really know who it is, god or demon, force of good or platform for evil. But it does know what it is not, though we may have forgotten: it is not the internet. That is a hardware network made up of servers, fibre optic, microwave and comsats talking to each other in TPC/IP, a protocol designed by Robert E. Kahn and Vinton Cerf. The Web, which consists of interlinked data, rides on the internet. It is made up of electrons and talks to our browsers in HTML and HTTP, the mark-up language and transfer protocol written by Berners-Lee, who conceived the system as a permanent, incremental archive. As the Web grew, as services like search engines and wikis were launched to index and organise data, it became …continued »
