I started with capital of about $1,500, a princely sum for a student coming out of college, an amount I borrowed from my father.

We were in the market ahead of competition. We brought new products on the market ahead of competition. We rolled out our networks. We begged, borrowed, stole, put things out. And while they were never near perfect, they were first. And that gave us, to my mind, a lot of advantage.

All competitors are fierce competitors; Vodafone is the world's second largest company. We fight it each day. Idea Cellular is big and successful, too. Competition is competition; we are used to it.

I personally believe every country has the same amount of spectrum. It is not that India has less... It needs to be vacated from other places; that is what other countries have also done.

Even if the technology advances, I don't expect we will be allowed to sail around with 400-meter long container ships weighing 200,000 tonnes without any human beings on board. I don't think it will be a driver of efficiency - not in my time.

The Internet is a collective hallucination: one of the best humanity has ever generated.

In the next 10 years, I expect at least five billion people worldwide to own smartphones, giving every individual with such a phone instant access to the full power of the Internet, every moment of every day.

It is possible that the digital world may change the need for physical branches. We will continue to add branches incrementally, but we will reach a point - whether it is 1,500, 1,800 or 2,000 branches - where we will say enough is enough.
