I think it would be more useful if there was some criteria behind the list. Maybe there are, but I do not see what. It doesn't have to be exhaustive, there might be criteria like "not well known" or "representative of a certain idea".

This is a good (albeit exhaustive) list too: https://en.wikipedia.org/wiki/List_of_programming_languages_...

A more interesting list might be an <ol> with the first few languages to learn to cover the most good concepts.

But such a list would be a lot more decisive.

And if it was an objective measure, there would never be a least interesting language, because if there were, then it would be interesting for that reason.

Elixir is Ruby like wrapper to a prolog based syntax to do actor based programming. It's more of a mess trying to move Erlang's syntax forward than interesting, but ok.

Ponylang is listed as "--" instead of "concurrency as a primitive type".

I'm not sure I can trust anything on the list, so it doesn't motivate me to investigate further. YMMV
