(author of post here) I didn't get the impression from speaking with Martin that he was trying to gatekeep. He's spent a lot of time on github and in discord helping people learn Seed and MoonZoon. In the context of hiring, I think the signal he's talking about is the same for any minority language like Haskell or Elixir. If you're spending nights and weekends hacking in a language that's not widely used in industry, it's an enthusiasm signal. This was true for Python about a decade ago, even though it's an easy language to learn. If you hired python developers, it was a signal that you'd be getting passionate enthusiastic developers. As Rust becomes more adopted and hiring goes up, I think the value of that signal will go down. Rust certainly has complexity, but I don't think they're insurmountable barriers for any significant class of developers.
