My comment is all speculation --- I have always assumed that you can need to know either English or Chinese to be a software developer. Mainly because the bulk of resources are in English, except China which has a large enough population that it can sustain it's own ecosystem internally. I think the smaller your country is, and the software engineer population within it, the more you need to rely on English. E.g. I could see Russia and Japan having non-english speaking software developers, they have relatively small populations (<150M) but seemingly a lot of tech stuff going on. You can also see which languages technology blogs / documentation are usually translated too. Which is usually Chinese, Japanese, Russian. Unless I'm wrong, because I can't point to any examples off of the top of my head.
