White House: Future Software Should Be Memory Safe (www.whitehouse.gov)

On the one side I really like c and c++ because they’re fun and have great performance; they don’t feel like your fighting the language and let me feel sort of creative in the way I do things(compared with something like Rust or Swift).

On the other hand, when weighing one’s feelings against the common good, I guess it’s not really a contest. Plus I suspect a lot of my annoyance with languages like rust stems from not being as familiar with the paradigm. What do you all think?

I’d be surprised if C tooling wasn’t available to provide sufficient proof for a given statically-linked program.

Be prepared to be surprised then. If such tooling was available, why isn't it being used by the projects for whom it matters? Yes, there is tooling available, but all the big parties using them are admitting it's not good enough for them. Those tools help, but they do fail in the "sufficient proof" department.

For some follow-up reading:

They all share the same basic facts: C and C++ are inherently memory unsafe. If any of them could've "just prove[n] your programs are memory safe", I think they would have.

Oh, my dear, sweet, summer child. Welcome to capitalism, and the rule of "good enough." Static code analysis tools cost money, and take time to run. I've yet to work at a company that didn't have a documented process for entirely bypassing QA in urgent situations; although, when I contracted with the USFS, they were much more reluctant to cut corners - that was under a Democrat president; when Republicans took charge, they cut a lot of things, including software quality controls.

But - as I said - I haven't touched C in decades, so I can't refute your claim that such tools don't exist.
