We live in a highly competitive world - and we Indians have to struggle to catch up. So modesty is necessary, even if there is also a need for a certain amount of national pride. When it comes down to it, we have managed our country's economy poorly for long enough. There is really no reason to now think that we can conquer the world.

I think the environment has become more competitive. That has made Indian industry more concerned with a) its customers, b) the quality of its products, and c) its brand image in the marketplace.

Google, I think, in some ways, is more competitive and certainly is trying to build their own little version of Facebook.

We're very focused on making News Feed really good, making our photos experience really good, making messaging really good, and creating great location apps. That's the nature of a platform business of our scale. Most companies that are relevant to us will have some overlaps in some competitive way.

If we can keep our competitors focused on us while we stay focused on the customer, ultimately we'll turn out all right.

The strong live and the weak die. There is some bloodshed, and out of it emerges a much leaner industry, which tends to survive.
