Google search chief Amit Singhal outlines his vision

Google search chief Amit Singhal says that the company is operating at the cutting of language. And yet, there is still so much to learn about how language and computing can be combined to bring the rich content of the web to the world.

Even so, he tells the BBC's Richard Taylor, within 15 years everyone - from the King of Spain to the farmer in Africa - will have equal access to the web.

"Everyone in the world will have the same level of connectivity," he says.
