Fair enough. But it's incompatible with the claim made in the article - that cryptography is science and not engineering. It can be both. In fact, it's likely that it will split to two disciplines in future, much like probability and statistics. Cryptography reminds me of cellular automata in that both are made up concepts that you can have lots of fun with, if you enjoy that kind of thing. I prefer CA because of its visual nature.
