Well it took me longer to get comfortable with Rust than Go, and I also had to learn actix (actor style framework in rust) to do the same high concurrency programming. But once the time investment is put in, I definitely consider Rust to be the more productive language. Once async/await stabilizes and the rest of the ecosystem catches up and becomes a little bit more ergonomic to use, I would say Rust will be in a good position.
