Bill Joy is one of the co-founders of Sun Microsystems, the company that brought us lots of products among which Java and Solaris. Bill quit Sun this september. Wired published an interview with Bill Joy in which he makes some interesting notes: You've been famously cool about Linux. Re-implementing what I designed in 1979 is not interesting to me personally. For kids who are 20 years younger than me, Linux is a great way to cut your teeth. It's a cultural phenomenon and a business phenomenon. Mac OS X is a rock-solid system that's beautifully designed. I much prefer it to Linux.
What about the open source idea in general? Open source is fine, but it doesn't take a worldwide community to create a great operating system. Look at Ken Thompson creating Unix, Stephen Wolfram writing Mathematica in a summer, James Gosling in his office making Java. Now, there's nothing wrong with letting other people help, but open source doesn't assist the initial creative act. What we need now are great things. I don't need to see the source code. I just want a system that works.
And that beats Windows. My goal is to do great things. If I do something great, maybe it'll beat Microsoft. But that's not my goal. I find Windows of absolutely no technical interest. They took systems designed for isolated desktop systems and put them on the Net without thinking about evildoers, as our president would say.
