the older and more experienced I get I increasingly see that pattern: those who don't really know/understand Unix, vi or Lisp seem doomed to reinvent them, typically poorly, more expensively, more convolutedly, more bureaucratically/monopolistically, etc. Not to say they're perfect in all ways, or 'complete', only that I've lost track of the number of times where someone went with a much more complicated/expensive/indirect/expensive solution when they would have been better off with something provided/encouraged or exemplified by the patterns of Unix, vi or Lisp.
