Realistically much of the most reliable software in the world was written in C. Robustness is more so a function of coding style and engineering practice than it is of the programming language chosen.

Of course you could argue that on average, most programmers are not going to have the right practices and skill, so on average you should prefer Rust. But that's unrelated to the argument I was making, and in any case not a very interesting point in my opinion.

Adding that with a principled approach, I don't even see much of an issue with doing manual creates and deletes in a object-graph type app, with many unstructured lifetimes. Sometimes that might just be required, and then the complexity is just there either way. Having to cleanups manually or not doesn't change anything about that. It's a bit more cumbersome to get everything right when doing it manually -- sure.

The problem is mostly people graduating from school thinking that somehow there is only stack and heap, and malloc/free is how you do heap. That view completely ignores that the essence of programming systems is mostly to understand the machine, and then doing conceptual and architectural work on a solution (and also on a problem). The act of writing actual code is then mostly just translating those concepts into the digital world verbatim.

Conversely, most of the high impact bugs are also written in C and C++, because they rely on "coding style and engineering practice" to be correct. Rust raises the floor on this by a lot.
