I'm not so sure about this, it recently came up in discussion with a former teacher of fine, here's what I said then: To the linguistics question I just had a discussion about this with my boss (who's a linguist by training, currently on leave from his PH.d which has something to do with Greek, he's also been programming a lot longer than I have). One of the points he had was that the Sapir–Whorf hypothesis doesn't just say speaking German affects how you think in German, it affects how one thinks as a whole. To that we're both a bit skeptical, being a programmer probably affects ones cognition (or ones cognition causes one to be predisposed to becoming a programmer, whichever!), but the specific language one uses... probably not. On the other hand, within programming it's clear that different languages (or at least their communities) have different personalities. A good example of this is Python and Ruby. Semantically these languages are remarkably similar (in the context of all programming languages), however their communities have seized upon the small differences and as a result the cultures (accepted best practices and such) are fairly different. Another good example of this is what are known as "design patterns", which were originally supposed to be a language-neutral way of expressing how code could be architected, however in practice some of these really make no sense with certain languages, because e.g. the language has builtin-features which obviate the need for such things.
