> Programs written in Rust don't last more than a couple months.
They last just fine much longer than that, you may just have to upgrade your compiler if you compile from source (doing so is a single command, takes about 30 seconds max, and new versions are backwards compatible so code targeting older compiler versions will still work). Importantly, you generally do not need the Rust compiler at all if you only wish to run Rust applications. You can usually download a pre-compiled binary distributed by the program authors. Applications (not libraries) requiring a recent compiler / language toolchain and updating as and when is convenient to them is hardly unique to Rust.
