Bill Gates
Co-founder and Chairman of Microsoft, and founder of the Bill & Melinda Gates Foundation.
Bill Gates is a very rich man today ... and do you want to know why? The answer is one word: versions.
About 3 million computers get sold every year in China, but people don't pay for the software. Someday they will, though. As long as they are going to steal it, we want them to steal ours. They'll get sort of addicted, and then we'll somehow figure out how to collect sometime in the next decade.
If something is expensive to develop, and somebody's not going to get paid, it won't get developed. So you decide: Do you want software to be written, or not?
Programs today get very fat; the enhancements tend to slow the programs down because people put in special checks. When they want to add some feature, they'll just stick in these checks without thinking how they might slow the thing down.
