You can but then it's a work to do for each language. That's how science got reinvented in multiple places before virtually all papers start to be written in English and shared in international journals.
> You make it sound like you can't change it. Like older languages are set in stone.
Do you suggest adding a layer of dependencies and complexity to the build systems to preprocess the source code to make it compilable by GCC/clang/Visual?
And it would make sharing open-source project limited to their language speakers, until you have someone translating the project. And what happens when that person can't keep up with the pace of the original project? Just look at all the material in Chinese on Github that is just inaccessible to non-chinese speakers.
All engineering schools in France require a minimum score on tests like TOEIC/TOEFL (in my school it was TOEIC 785 / 990, got raised to 800). High school graduation requires a CEFR level of B2 (even if not all students reach it) in English.
> I know if I had to learn french in order to code, I wouldn't be a programming. And I'm sure it's the truth for the vast majority of american programmers.
Except that a lot of the world is already exposed to English in movies, series, books, websites, memes, YouTube, work. American are not exposed to French, German, Japanese, Chinese.
