It's not a good comparison. In the very, very long-term, the "fit" inventions do tend to win out, but that says nothing about the processes by which they were built. That is, unless you get really loose with the definition. If I'm designing a bridge, and I come up with 10 blueprints, and select the best one...that's not really an evolutionary process, and neither would it be if 10 different engineers came up with a blueprint. If we build 10 bridges and wait for nine to collapse, well, that would be an evolutionary engineering process. (Again, over centuries and centuries, that very thing occurs.)

A better analogy would be comparing the marketplace with a harsh environment. There, Linux survives for a mundane reason--just like mammals needed less heat from the atmosphere, linux needs less money from its customers. So, it may win out in the end.
