Around '93, '94, the conventional wisdom about the Internet was that it was a toy for academics and researchers. So it was very, very underestimated for about two years.

We have never lived in a time with the opportunity to put a computer in the pocket of 5 billion people.

On the back end, software programming tools and Internet-based services make it easy to launch new global software-powered start-ups in many industries - without the need to invest in new infrastructure and train new employees.

With lower start-up costs and a vastly expanded market for online services, the result is a global economy that for the first time will be fully digitally wired - the dream of every cyber-visionary of the early 1990s, finally delivered, a full generation later

Learning to code is the single best thing anyone can do to get the most out of the amazing future in front of us.

More and more major businesses and industries are being run on software and delivered as online services - from movies to agriculture to national defense.

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.
