That's why the really good, elegant, clean systems (and I don't mean
just UNIX) always spring from a very few minds.  One, two, perhaps
three, probably not more.  The actual implementation may be the work of
many, but the design must be the work of only a few, preferably only
one.  (It helps if the implementation is, too, but systems are getting
a bit big for that nowadays.)

Fred Brooks talks about this a bit (in The Mythical Man-Month, which I
think everyone interested in any aspect of systems design should read).
