Why Apple and Google Made Their Own Programming Languages

Gamoid writes: This Business Insider article looks into the state of Google Go and Apple Swift, highlighting what the two languages have in common — and why tech companies would bother involving themselves in the programming language holy wars. From the article: "One fringe benefit for Google and Apple is that making your own programming language makes recruitment easier — for instance, since it builds a lot of its own server applications in Go, Google is more likely to hire a developer who's already proficient in the language since she would need less training."

Right. Apple created Swift because Objective-C was a nice language for the requirements of '90s computing, but is starting to be limited by its C heritage. They needed a more modern language that interoperates very well with Objective-C (because they have a lot of legacy Objective-C code that isn't going away any time soon) and this required making a new language because there weren't any good contenders available. MacRuby is the closest, but falls short in a number of areas.

Google didn't create Go as the result of some corporate masterplan, a small team at Google created it and managed to get buy-in from some other groups at Google. It's still far from the most widely used language for new projects inside Google, but it does have some advantages (though is slightly let down by Rob Pike's refusal to accept that some people who are not Rob Pike have had good ideas in the last 30 years).

The recruiting thing can't really work. It would only really make sense if people would learn a cool language and then discover that there are very few places where they can work and use it. This is sort-of true for something like Erlang or Smalltalk, but Swift is fairly widely used by people developing for iOS and OS X (and would probably not be worth Apple's effort in developing it if it weren't). If the language is successful enough that enough people are learning it to significantly affect the pool of potential applicants for a company the size of Apple or Google, then enough other companies are likely to be using it that it isn't a significant benefit.
