(I read your sentence with an implied subject, which is fine for casual grammar, but the second phrase is subjunctive because the first is, so "do not" and "don't" fit poorly there, even for casual speech.)

Just imagine everything in a different language. Hydro Quebec had an application in French.

This is more evidence that community is key for programming. Community even trumps native language!

That sentence did felt a bit awkward.

All mainstream programming languages are based on English and so are the majority of resources. Even APIs for the operating systems we use and the protocols for communication.

Everything is pretty much exclusively English. It'd be such a huge disadvantage.

So, you're saying it's inconceivable that someone could be competitive in the field without English skills, not that programming in another language period is inconceivable. I'm totally down with that.
