I've come to accept that i wasn't really developing in "rust", but in "tokio-rust", and stopped worrying about async everywhere (it's not fundamentally different from what happens with other lang having async).

Why the need for going back to threaded development ?

1. Async Rust is extra stuff for engineers to learn and maintain in their heads.

2. Async Rust has a lot of papercuts.

3. Very little code actually needs async. For example, in an API server, every request handler will need a database connection so the concurrency is limited by the database.

I wrote the Servlin HTTP server in async rust, to handle slow clients, but it calls threaded request handlers.
