> From the perspective of high level application development, I can't see a technical use case for a language other than Rust these days.
There really isn't anything other than web that covers that use case, sadly.
C# still has runtime exceptions and race conditions.
With Rust, once you figure out the borrow checker (which is honestly pretty simple), you're at least as productive but with fewer bugs
Additionally, I don't think C# is that simple anymore. By now it has so many features added and the list is still increasing this day. Rust is more difficult to get productive, but the actual language complexity isnt that big.
LLMS makes onboarding to Rust much easier though if you even still write code yourself. I don't think the productivity difference is that large.
