For platform stuff that has speed and correctness as the highest priority? Absolutely. Things like http proxies, message queues, shared infrastructure makes sense to be done in Rust.

For writing a normal networked http/rpc/event stream service Go is probably more than good enough. It’s not a winner-take-all market.

A great example imo is Buoyant’s Linkerd. Rust dataplane proxy as well as a control plane written in Go. Two different requirements for each of those services drove the language requirements
