I have invested in four social networks. More than any other. But that's in Russia and Poland.

The company that creates one global social graph will be very important going forward. It will be Facebook, with maybe 2-3 local social networks able to sustain competition long term.

Social is a better way to interact with digital world. It is better than search. Implications for... everything. Total change.

One of the companies that we've invested in is called Facebook. In only two years, between 2009 and 2011, the information exchanged between people increased 28 times. And that cannot be explained by new people joining Facebook.

There is a significant momentum behind the social Internet. A wide range of public investors were very enthusiastic about that.

Fundamental physics is like an art more or less. It's completely non-practical, and you can't use it for anything. But it's about the universe and how the world came into being. It's very remote from your daily life and mine, and yet it defines us as human beings.
