SAN FRANCISCO — Twenty-seven years ago, Tim Berners-Lee created the World Wide Web as a way for scientists to easily find information. It has since become the world’s most powerful medium for knowledge, communications and commerce — but that doesn’t mean Mr. Berners-Lee is happy with all of the consequences.

“It controls what people see, creates mechanisms for how people interact,” he said of the modern day web. “It’s been great, but spying, blocking sites, repurposing people’s content, taking you to the wrong websites — that completely undermines the spirit of helping people create.”

So on Tuesday, Mr. Berners-Lee gathered in San Francisco with other top computer scientists — including Brewster Kahle, head of the nonprofit Internet Archive and an internet activist — to discuss a new phase for the web.
