Your warning about niche technology is fair, but a Stack Overflow survey is NOT representative of what's going on in the real world. Better, more objective app

Your warning about niche technology is fair, but a Stack Overflow survey is NOT representative of what's going on in the real world. Better, more objective approximations can be gained by reviewing download stats of centralized package managers. Elixir uses hex. Rust uses crates.io. Python uses pypi. Node uses npm. Review download stats and then decide how popular libraries/languages are. It takes time for technologies to catch on. Elixir and Rust both are relative drops in the bucket in respects to industry adoption, making it difficult for practitioners with the languages to continue using them beyond their current employment. Web development often acts as the foot-in-the-door, and Elixir's Phoenix is doing superbly well in this domain. However, Elixir's got an even more impressive position for data engineering related work.
