I've been programming in Erlang since 1991, every day; and that has been my intention all the time. I've done things in Haskell, Rust, Elixir, etc.. over the years. Strong typing is extremely valuable but what it all boils down to is where I have the most fun. Erlang is the prog.lang that gives me most joy and I plan to continue hacking Erlang, at least, until I retire in a few years.
