So far most respondents have gone completely off-subject here.

In hardware systems redundancy is critical for safety.  In software
systems redundancy is bad because, as you and the paper suggest,
redundancy makes for bugs.  The principle for software is both
normalization, DRY (do not repeat yourself) and ZIP (zero intolerance
for plagiarism).

As always, I enjoy your interesting posts.
