I had a senior dev in my previous team who pushed to write microservices for a web SaaS in rust. We already had some in Go and it worked phenomenal. Easy to learn, write, maintain, effing fast and wonderful tooling around graphQL. His only argument was "Rust is a better language and it's memory safe". That sums up the interactions I have with rust fanboys quite well. No one in the team could do rust, the added headaches around memory safety have no benefit for services like this at all and there's no tooling or hiring benefit as well (quite the opposite I guess). There wasn't a single sensible argument to be made for rust imho. I overruled him on that of course.
