Choice of language has much larger implications than you are implying. Yes, every language is turing complete. Now write a regex engine in pure "turing machine". Sucks, doesn't it? This is known as the "Turing Tarpit". Every language has unique strengths and weaknesses and it's absurd to pretend they're all kinda the same. I wouldn't write a website in C. I wouldn't write a robot arm driver in PHP. I wouldn't write anything more complicated than a throwaway script in bash. I don't mean to be disrespectful, and perhaps I didn't read your reply right. But it seems to me if you don't differentiate languages, then you either don't have enough knowledge of and exposure to various programming techniques and language design ideas, or you're making an argument in bad faith.

I think you do your point a disservice with your examples. General-purpose programming languages are nothing like Turing tarpits. > I wouldn't write a website in C. With appropriate libraries, why not? The safety issues might be a problem, but you could sandbox it. > I wouldn't write a robot arm driver in PHP. I would. It's general-purpose enough to speak binary protocols without too much hassle, though it'd be more fun to use something else.

  I have written a web site in C about twenty years ago, and it was terrible. Absolutely Turing Tarpit category, the language is just completely inadequate for this problem and so you spend all your effort trying to build something which is suitable out of the language, which again, yes, Turing Completeness, of course it's technically possible but it's a bad idea. Web sites are full of strings, and C doesn't really grok strings. Not in the way WUFFS doesn't grok strings (there are no strings in WUFFS, it has no string type, it's not a general purpose language it's not for that), more like the way New Forest ponies don't grok traffic laws.

    Many high-level languages with good string support are implemented in C. The C standard library sucks but it's not your only option for handling strings.
