One of the things I like about the computer that I use is that I can write a program on it or I can download a program on to it and run it. That's kind of important to me, and that's also kind of important to the whole future of the internet... obviously a closed platform is a serious brake on innovation.

I hope we will use the Net to cross barriers and connect cultures.

AI is not just heading for our industry, it will radically change the machinery we use in marketing.

We can't blame the technology when we make mistakes.

The more you enter, the more you become locked in. Your social-networking site becomes a central platform - a closed silo of content, and one that does not give you full control over your information in it. The more this kind of architecture gains widespread use, the more the Web becomes fragmented, and the less we enjoy a single, universal information space.

As more and more people awaken to the threats against our basic rights online, we must start a debate - everywhere - about the web we want.

I'm very aware there are lots of other people who are just bright and working just as hard, with just the same dedication to make the world a good place.
