Most people just want to get something done and reach for the tools that will most straightforwardly and simply get them to their destination. Niche stuff doesn’t have the market fit because you’ll always have a hard time finding people to work on your product that don’t cost twice as much as everyone else, unless it’s 10x faster gtm / 10x cheaper. Seems obvious enough.

Personally? I like good typesystems and very sharp tooling. It has seemed to me that Elixir has neither, and doesn’t really offer me a particularly big advantage that would outweigh those disadvantages.
