I also think that the largest factor is cultural. But my conclusion from this is not that one should import it with a new language while pretending achieving similar results is not possible otherwise. This just gives an excuse for not caring for the existing code anymore, which I suspect is one reason some parts of the industry like Rust ("nobody can expect us to care about the legacy code, nothing can be done until it is rewritten in Rust")
Of course highly correct C code is possible [1]. But ADA makes it easier. Rust makes it easier. You can write anything in any language, that is _not_ the argument. How could you plausibly advocate for a culture that invests a lot of effort [1] into making codes correct, and not also advocate for tools and languages that make it easier to check important aspects of correctness? A craftsman is responsible for his tools. Using subpar tools with the argument that with sufficient knowledge, skill and an appropriate culture you can overcome their shortcomings is absurd.
Rust is also often not the right tool. I looked at it fairly deeply some years ago for my team to transition away from Python/C hybrids, but settled on a fully garbage-collected language in the end. That was definitely the right choice for us.
