   This is a good argument for only working on free software, but not
for eliminating copyright on software.  I for one think programming
languages can be quite usefully employed for conveying information by
themselves, particularly if you want to communicate with precision about a
particular algorithm or set of algorithms (or variations among
implementations of an algorithm).  Hence I might write a text on a family
of algorithms and include program source that does much of the explanatory
work.  If I do a really good job, that text can still be useful far in the
future.  I would say it would roughly correspond to how mathematics
textbooks age gracefully when well-written, even with changes in notation
and vocabulary.  CS in not old enough as an independent field to really
judge this yet, though I'd think Knuth's texts are a good start.
