mspohr shares a report:* When Sir Tim Berners-Lee invented the world wide web in 1989, his vision was clear: it would used by everyone, filled with everything and, crucially, it would be free. Today, the British computer scientist’s creation is regularly used by 5.5 billion people – and bears little resemblance to the democratic force for humanity he intended.

Since Berners-Lee’s disappointment a decade ago, he’s thrown everything at a project that completely shifts the way data is held on the web, known as the Solid (social linked data) protocol. It’s activism that is rooted in people power – not unlike the first years of the web.

This version of the internet would turbocharge personal sovereignty and give control back to users. Berners-Lee has long seen AI – which exists only because of the web and its data – as having the potential to transform society far beyond the boundaries of self-interested companies. But now is the time, he says, to put guardrails in place so that AI remains a force for good – and he’s afraid the chance may pass humankind by.

• Berners-Lee traces the web’s corruption to the commercialization of the domain name system in the 1990s, when the .com space was "pounced on by charlatans." The 2016 US elections, he said, revealed to him just how toxic his creation could become. A corner of the web, he says, has been "optimised for nastiness" – extractive, surveillance-heavy, and designed to maximize engagement at the cost of user wellbeing.

His answer is Solid, a protocol that gives users control through personal data "pods" functioning as secure backpacks of information. The Flanders government in Belgium already uses Solid pods for its citizens. On AI, his optimism remains dim. "The horse is bolting," he says, calling for a "Cern for AI" where scientists could collaboratively develop superintelligence under contained, non-commercial oversight.
