I think you're not considering enough ways in which one technology can be superior to another.

Ruby wins for the web not because it is faster _at executing code_, but because the combination of Ruby and Rails is faster _at iterating new features_; the optimization which has led it to win is performance of programmers, not code.

Likewise, Windows is inferior to Unix as an OS design -- but it is vastly superior to (non-MacOS) Unix in the time it takes to get a semi-technical user from a machine still in the box to a machine which can do the things most users care about (browse the web, edit documents, and so on).

In the long run, which matters more? Machines are getting faster much more quickly than programmers or users are getting smarter...
