From what I'm reading in your response, we agree.

When a project grows in complexity, age, number of contributors, poor review culture, complex requirements, or any of 101 different things that can make a project hard, then it is hard to avoid memory safety bugs. This covers like 99% of non-trivial projects.

If your software projects are very simple, then it is easy to write simple C programs that do the job well. This is what I said before. If your project is simple, boring, and straight-forward, using C is just fine. It is complex projects where the use of C can become a problem (and complexity can sneak up on you from an unbelievable number of sources).

I would not say we agree with respect to your last point. I think also very complex C programs can be made memory safe, when this is a design goal from the beginning. That complexity can make this harder is true also for Rust, where people then often use unsafe, or, alternatively, re-engineer large parts of their project to get the structure right. C gives you the same choice at this point, but it may be more common to pick the unsafe path because memory safety is not valued high enough to justify the refactoring cost, so people often accept safety issues instead of fixing the design issues in the program.
