I personally don’t see the appeal of Go. With Rust, I can write a concurrent, safe, and C-performant program with modern programming features like matches, generic programming, and a dedicated package manager (never understood go get). To boot, Rust has a strong ecosystem and the fastest web framework out there (Actix). It takes roughly the same amount of code to do networking stuff in Rust and Go, but with Rust it is more performant and I can sleep better knowing that if it compiled, it is at least safe and won’t have any concurrency bugs.

A quick back of the paper example, I am doing Advent of Code this year and the same exact implementation took 40 ms in Rust and 350 ms in Go. Not to mention the Rust implementation, despite being the same semantically, was more concise and clear due to Rust’s extensive Iterator trait methods. A small difference you might say, but it’s just one less reason for me to switch.
