Yes, there will always be certain limitations as you've accurately mentioned. However, as a platform for writing networked web services, I think the Erlang VM is stellar. Compared to other languages, such as Go, Python, Rust, etc, the conceptual models in Erlang (processes, message passing, supervision trees) and how they all work, map better to the web problem domain. As far as the slow parts, like you said, there are plenty of choices of integrating other languages.
