The title of the post is "Tokio/Rayon Trap" - those are two very well known Rust libraries.

(in case you missed it, authors mention them later and explain what they do: "Use Tokio for I/O, and send CPU-bound work to a dedicated thread pool like Rayon.")

Authors have whole section ("The Work-Stealing Myth") on Erlang.

Author's proposed solution ("Project Tina") is a new programming language written in Odin.

How on earth do you read this all and start talking about Javascript problems instead?

There was a single mention of nodejs (and also python). But I doubt this person read the article.
