I understand where you're coming from. I hear the "bigger fish to fry" sentiment often. The point about distributed data races is a good one.

At one point I did a comparison between a mono/Nancy web service and the same web service, feature for feature, built in NodeJS, Rust/rocket, and Go. I built a few different endpoints that did different types of work and load tested them, profiled memory usage, etc. I know mono and perhaps Nancy weren't the best point of comparison, and it's been some time since, but Rust/rocket really impressed me then, including on axes like ease of development and code readability. The perf deltas I saw could matter quite a bit at scale, allowing for fewer/cheaper servers.

I've enjoyed using Rust for a few things since, personally, and am so far pretty unbothered by its shortcomings.
