I would say "the irrelevant case.."

Where Rust excels is in safety when using concurrency. Most web apps and APIs have a single thread used per request. I've also used async/futures that work fine without ownership modelling.

As for performance switching from Ruby/Python to Java/C#/Go will pay off not so much to then go to Rust unless it's a particularly high throughput or latency zensitive app in which case you'd already know it matters.
