In my recent post on LanguageEvolution, I mentioned that (spoken/written) language evolution is influenced by social factors. Language features suggesting affluence often win the evolutionary fight as speakers strive to sound more "cultured" or intelligent. Paul Graham has the following to say about programming language research:
Research imposes constraining caste restrictions. In any academic field there are topics that are ok to work on and others that aren't. Unfortunately the distinction between acceptable and forbidden topics is usually based on how intellectual the work sounds when described in research papers, rather than how important it is for getting good results.
So, social factors seem to be affecting language designers as well. If it doesn’t show "intellectual affluence", it’s apparently (according to Graham) not likely to show up in research. In this same section, Graham says that he is excited that many new languages are being created by "hackers" these days (Perl, Python, Ruby, etc.) and that there are some innovative ideas coming out of these languages. In the context of computing history, this represents a step toward empowerment on a wider scale. Not quite "the masses", but closer.
If you’re at all interested in this kind of thing, the full article is definitely worth a read.
