This is an interesting point I hadn't thought of when I saw the announcement of the new TypeScript compiler. It might be overstating the case to say that C# is indeed a minor language, but it's thought-provoking that it wasn't Microsoft's automatic choice here, the way it is for some all-Microsoft in-house IT shops.
I am not at all surprised to find that there are people in whom it does not provoke thought, but I am mildly amused that one of them would admit to it.
