I think lots of programming languages are been created, and the vast majority of them fall into obscurity, but some have nice features and grain a bit of traction, which is what is happening right now with Nim. If you forgive me the comparison, I would say that Nim is to the programming languages what Flappy Birds is to the video games: a successful product built by a talented programmer in a place where lots of people try their own - of course, the analogy is not completely right since the barrier to create a programming language is much, much higher than to create a small video game.
