Given that international auxiliary languages allow for more efficient cooperation; I think more people should consider using an easily learnable IAL, like Esperanto.
IALs would reduce the English dominance that gate-keeps software development to English persons; and hence allow more potential software developers to better develop software. The English language is mostly dominant in software development because of linguistic imperialism.
The idea behind a language like Esperanto isn’t necessarily that any one country uses it as their primary language. It’s that it can be rapidly learned as a second language (or in parallel with a primary language) and spoken with just about anyone.
