I agree that there could be languages better suited for general purpose programming than Rust. However eventually most succumb to the ecosystem critical mass.

I agree that there could be languages better suited for general purpose programming than Rust. However eventually most succumb to the ecosystem critical mass. Whether you end up using ocaml, or pony, or elixir or whatnot, you'll soon hit that wall, where you can't hire developers easily enough (or move them between teams), or you can't find that answer on stack overflow easily enough, or have somebody fix that toolchain bug for you, or find a workaround that language or stdlib issue you're blocked on. Rust, for all its flaws and difficulties, has reached that critical mass, and even people who are not entirely sold on it, may end up choosing it just because overall it makes more sense than many of the alternatives.
