Rust hasn't grown in scope very much since its release, but in places where it has grown, particularly async and unpin, I find that there features interact very badly with lifetimes and borrowing. I am often forced to ditch borrowing across async method calls and to put everything in Arcs, even when the lifetime is well-defined and it could be easily used if it had been scoped threads instead of futures. I fear that newer features will be incompatible with older ones in a similar way, but fortunately there are no such features on the horizon.

Considering all that, I still see Rust as the most sane choice for writing native programs. I don't really want a "better C", I want to write memory-safe software with confidence, and that means static analysis or a thick safe runtime, whatever is more suitable for the use case.
