Tim Berners-Lee encouraged fellow scientists at his former particle physics laboratory in Switzerland to look to the future. “The rate of development and innovation on the Web is actually getting faster and faster all the time,” Berners-Lee said at a ceremony at the European Organization for Nuclear Research, known as “CERN.” “The Web is not all done. It’s just the tip of the iceberg.”
