Exactly so. I spent several decades doing software development at GE's
Corporate R&D Center, and I had ample proof that both of those things are
true. I think the phrase you want in English is "fewer experiments you
need to perform," but you did see the principle.

Hear that, Linus? Off to the retirement home with you unless you "rm *"
your source tree and "go back to Baltimore and start over again as a
virgin." Actually I think that Linux is an example of major software
designed from the start to be rewritten in parts and to evolve as a whole.
no clean sheet of paper needed.
