By looking at HackerNews, Reddit etc to get a feel where the community (or bubble) is going. Then validating these information against what is actually happening in your company. And then it is mostly whatever you decide what you want to chose. So for me Rust was the main contender so I read stuff about it. But also Ocaml, F#, Zig or Nim are interesting to me. I think in the end my way to chose things is: Are there good libraries for the language I would want to learn? Does the language fit into my current workplace and would my colleagues be able to adopt the language as well? Does it fit into the culture? What is the operating risk to continue supporting the tools I chose for a team/company, If I were to leave the company?
