Thanks, that helps me understand. The problem for scientific users seems to be to achieve enough consensus about which language to use as an "obvious choice" that a bunch of other scientific users make packages. Since we are talking about "fast" languages like Nim and Julia, I wonder why R and Python have done so well with the scientific audience but C++, Java, C# and the like never developed anything quite comparable. Or did they and I just didn't notice?
