Perhaps, but Go’s threading model uses a lot more memory than Erlang and Elixer and Go’s threading is handled in public memory, whereas Erlang and Elixir processes are all protected in private memory. Erlang and Elixir’s supervision tree is also pretty damn great. OTP is solid and has been thoroughly proven. Elixir also handles dependencies much better than Go, in my opinion. I’m sure Go is nice too, but I don’t think the backhanded compliment about Cowboy, Erlang, and Elixir is warranted.
