> "Difficult to do well" and "creativity" does not equal "copyrightable". But how you express it is covered by copyright. A mathematical proof is not, but if you write it out so that it rhymes, that specific expression is. You can now state the same proof a thousand different ways, even those that rhyme differently. But all those original those of the same proof remain protected. I would tend to agree that copyright and patents are probably not a good fit for protecting software, and maybe a new framework is needed. But given the current means at hand, this decision is internally consistent.
