In my case if I were to use Rust for a personal project, that would be a clear case of thinking inside the box. I think this is because I use C++ a lot and Rust is more of the same, except with fewer libraries & domain support but safer and more restrictive. For something where one has the freedom to pick anything they want, I'd take advantage and use something more user-friendly and with even less restrictions like Python or Swift. Although for heavy lifting I may still reach for C++ because of the massive ecosystem. Languages like Rust or Ada with their heavy reliance on specific "annotations" to ensure safety are designed for professional teams that must fulfill certain quality attributes.
