People are so bad at driving cars that computers don't have to be that good to be much better. Any time you stand in line at the D.M.V. and look around, you're like, 'Oh, my God, I wish all these people were replaced by computer drivers.'

I hope to someday live in a world where there are lots more Silicon Valleys.

Over two billion people now use the broadband Internet, up from perhaps 50 million a decade ago, when I was at Netscape, the company I co-founded.

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

Technology is like water; it wants to find its level. So if you hook up your computer to a billion other computers, it just makes sense that a tremendous share of the resources you want to use - not only text or media but processing power too - will be located remotely.

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.

The multipurpose device will always fail.
