On HN every time the subject of language wars or platform wars or browser wars comes up, the idea also comes up that "everything is about the number of users". The self-reinforcing cycle is that the language/platform/browser with the most users also has the most development time put into it, which then attracts more users, etc.
Fine, I don't deny that the phenomenon exists. But I think that it's often overlooked that it's not just about the number of users. It's also about the quality of the users. If we could quantify "an excellent developer", I wouldn't claim that Julia has more of those than Python. But I'm convinced that Julia has more "excellent developers who are also excellent at numerics" than Python. I think the idea that the productivity as function of "developer excellence percentile" is a power-law applies even more strongly in multi-domain expertise situations, like numerical computing. So forget about 100x coders. The contributions of some people like Chris et al are closer to 10_000x as significant as that of an ok contributor.
It's not just about the quantity, it's also about quality.
