Assume mainstream adoption as used by around 7% of all github projects
Personally, I’d like to see Nim get that growth.
My problem is not with inclusivity but with promoting uptake. If you are familiar with the grammar or phonetic sounds or some of the vocab, you are more likely to find that language easier to learn.
Both English and Esperanto share the same problems of universal languages that I mentioned. English does have the advantage of number of speakers but it is a mess of a language for people to have to learn.
Again to reiterate my counter to universal languages, why not learn and potentially help revive your local indigenous languages. In a world where universal translation exits on our phones everybody being able to speak the same language matters less.
