The project isn't even public yet, has been under development for only a few months, hasn't had the opportunity to get wider academic eyeballs on it yet, and you're already calling it DOA. Nice.
Yeah, this seems like a real disingenuous complaint around a pretty incredible (and still super young) accomplishment. I would also assert that Elixir is an excellent language syntactically to work on data science-y projects. I'm really excited.
