I don't understand how this relates to R? It starts of saying R is bad (agreed) but then what it just goes off on a tangent about something unrelated without really explaining what's better. I've said this before and will say it repeatedly - R is a bad programming language by design to allow it to be a brilliant tool for stats/data science. Language geeks who approach data science from a comp sci background seem to miss this point - R works precisely because it's not a good language. I'm perfectly happy to discuss a better alternative but without first understanding why R is used so widely in the first place misses the point of the discussion
