It doesn’t really matter where you draw “the” line for mainstream languages, so much as that there is some reasonably drawn line between Go and Erlang/Elixir.

Well, just ask the Toibe index:

It looks like Elixier ist by far less popular than the other discussed languages.

I personally prefer the RedMonk rankings [1] over TIOBE, since TIOBE's entirely about Google hits, which lags as an activity indicator by a few years, because sites for languages that have stopped being used stay around for years. Also, Google hits counts are really noisy, especially for languages that have names that are also words, like Go and Elixir. RedMonk uses recent GitHub and Stack Overflow activity as a proxy for popularity.

In this case though, Elixir is still way lower, at somewhere around 30th compared to Go's 14th.

Huh, I'm super surprised that VB .NET is growing. I used it at my last job briefly for unfortunate historical reasons and we were trying to run screaming away from it as fast as possible to C#. It felt like the runt of the litter of the .NET ecosystem; so many things worked better in C#.
