As long as you give an escape hatch to access the Erlang VM, the rest is somewhat superficial. I am way more productive in Elixir than I am in Erlang, but that's probably because of the way my brain is wired. > very carefully constructed set of trade offs But also the VM has changed since 1980 (for example there are maps now) and the programming ecosystem has changed (we know what drives productivity in terms of how to effectively test, document, deploy, good documentation > separate header files), we also know more about things like how lexical metaprogramming is maybe not the best idea for IDEs or language servers, it's really tough to say that Erlang got everything right for time immemorial. And on some things Erlang hasn't moved yet (thankfully it seems like there's movement in documentation).
