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

An awful lot of successful technology companies ended up being in a slightly different market than they started out in. Microsoft started with programming tools, but came out with an operating system. Oracle started doing contracts for the CIA. AOL started out as an online video gaming network.

Big breakthrough ideas often seem nuts the first time you see them.

A very large percentage of economic activity is shifting online and it makes sense that there are more services that are going to charge. It also means there are going to be more people willing to pay.

My own theory is that we are in the middle of a dramatic and broad technological and economic shift in which software companies are poised to take over large swathes of the economy

China is very entrepreneurial but has no rule of law. Europe has rule of law but isn't entrepreneurial. Combine rule of law, entrepreneurialism and a generally pro-business policy, and you have Apple.

Companies in every industry need to assume that a software revolution is coming.
