Your let's redo this in Rust made me wonder if generative AI will also be susceptible to software fads. One LLM writes a few blog posts extoling a new framework/lanaguge. Other agentics read these and get 'influenced'. Then they start clamoring for 'lets redo this in X!'. Can't wait to see it. /g
You can get 80% there with rust which is what is impressive. Then you have a reference implementation that you can always check against. If a Rust library have 0 unsafe, i dont care if it is written by a dog, it still have 0 UB.
UB is especially bad but also not as big as all other concerns combined. Two of the most reliable software ever to exist, curl and SQLite, are C/C++. There are also cases in system programming, drivers etc where the unsafe is necessary and then your code is only as good as the boundary, and lots of bugs can seep in. Another issue with Rust is ecosystem - the dependency trees required to do fairly basic things are often deep and vast, meaning other risks.
That said if something like rsync was written today, I still think Rust may be a better choice. Mainly because a 95 percentile skilled Rust programmer is less dangerous than for C. The people that are skilled enough to be trusted with C are few and diminishing every year.

Elon announces that spacex wrote its AI software in C. And now suddenly, C has become the new (old) kid on the block. Now we have folks saying, lets redo this in C as it gives you full power over the machine since we are 10x engineers. Earlier it was rust this or rust that. So, fads work both ways.
