Facebook is at the forefront. It's the company that can fundamentally change the way information is being exchanged and processed. It can be the basis for artificial intelligence to develop over time.

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.

I have this ratio that if you divide age of entrepreneur by market cap of company. For Facebook it's one. Every year of his life Zuckerberg has been making $1 billion for investors.

I think there's a time to be private and a time to be public, and I think that companies like Facebook and Groupon are basically transformational companies. You don't come across them very often, and I'm pretty sure that they can continue to grow for a long time even being public.

I think top scientists need to be compensated at a different scale in society. Somebody with experience will tell you that true scientists are not motivated by money - they are motivated by the quest itself. That is true. But I think an additional recognition will not hurt.

It is hard to think of practical applications of the black hole. Because practical applications are so remote, many people assume we should not be interested. But this quest to understand the world is what defines us as human beings.

Kai-Fu's Innovation Works is the top very-early-stage fund in China. We are proud to be an investor, and hope that IW will help to produce in China companies on the scale of Facebook, Zynga, or Groupon.

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.

Science is one of a handful of things that defines us as a very special species. It is amazing how far we have been able to get and how accurate our predictions are. I think understanding how the universe was born is very important. It really gives us a perspective on many things.

Story was that human civilization started to develop with first social network. Emerged where population concentration was high. Helped propel to where we are now. Facebook is next step of creating a huge human brain to embrace hundreds of million, possibly billions of people.

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.

The largest newspaper in the United States is only reaching 1 percent of population. We are kind of assuming that 'Wall Street Journal,' 'USA Today,' and other newspapers are very important. Yes, they're extremely important, but only to 1 percent of the population on a daily basis.

We monitor close to 50 companies globally that can be potential investment opportunities. I'd like to see DST as a significant global investment company in the Internet arena.

You know among people who kind of travel a lot and have exposure to the United States and some other countries, they do have accounts, but you know, Russia is not exactly the place with multiple language skills so local networks kind of have an edge.

I'm just focused on exploring new opportunities.

You have to travel globally today to know what's going on and maintain an edge.

The problem is that modern fundamental physics is so far from you and me. The mathematics has become so much more complicated that you need at least 10 years to understand it. Fundamental physics has advanced so far from the understanding of most people that there is really a big disconnect.

Facebook can be an accumulation of different intelligences.

Facebook didn't know how successful Zynga would be.

Facebook is a platform inside a platform.
