The dream behind the Web is of a common information space in which we communicate by sharing information.

What is a Web year now, about three months? And when people can browse around, discover new things, and download them fast, when we all have agents - then Web years could slip by before human beings can notice.

One way to think about the magnitude of the changes to come is to think about how you went about your business before powerful Web search engines. You probably wouldn't have imagined that a world of answers would be available to you in under a second. The next set of advances will have an different effect, but similar in magnitude.

We shouldn't build a technology to colour, or grey out, what people say. The media in general is balanced, although there are a lot of issues to be addressed that the media rightly pick up on.

The Web as I envisaged it, we have not seen it yet. The future is still so much bigger than the past.
