Matt Godbolt sold me on Rust (by showing me C++)
The point I'm sure was to prevent the checks from incurring runtime overhead in production. Even in release mode, the overflow will only wrap rather than trigger undefined behavior, so this won't cause memory corruption unless you are writing unsafe code that ignores the possibility of overflow.
The checks being on in the debug config means your tests and replications of bug reports will catch overflow if they occur. If you are working on some sensitive application where you can't afford logic bugs from overflows but can afford panics/crashes, you can just turn on checks in release mode.
If you are working on a library which is meant to do something sensible on overflow, you can use the wide variety of member functions such as 'wrapping_add' or 'checked_add' to control what happens on overflow regardless of build configuration.
Finally, if your application can't afford to have logic bugs from overflows and also can't panic, you can use kani [0] to prove that overflow never happens.
All in all, it seems to me like Rust supports a wide variety of use cases pretty nicely.

Automated reasoning and generative AI: Harness creativity with formal verifications
Modern software verification employs various approaches, each offering different trade-offs between ease of use and strength of guarantees. AWS contributes to the open source program verification tools used in the previous examples. Dafny and Kani represent two powerful approaches to program verification. Let's see how they work in practice before connecting the dots between automated reasoning and generative AI.

Isolating complexity is the essence of successful abstractions
I agree with what you're saying, but some context:
> I'm not aware of one for rust, but there is a lot of progress in this area
https://github.com/model-checking/kani is probably the best known one, I believe there are a few others.
> (I'm not sure what rust allows, particularly in unsafe).
You can't "cast const away" in Rust, even in unsafe. That is, you can do it in unsafe, but it is always undefined behavior to do so. (I am speaking about &T and &mut T here, const T and mut T exist and you're allowed to cast between those, as they have no real aliasing requirements and are really just a lint.)

Re-fixing Servo's event-loop
There's a model checker that can directly verify Rust code, Kani https://model-checking.github.io/kani/ - I wonder if Servo could use it in this case?

The Wizardry Frontier
Nice read! Rust has pushed, and will continue to push, the limits of practical, bare metal, memory safe languages. And it's interesting to think about what's next, maybe eventually there will be some form of practical theorem proving "for the masses". Lean 4 looks great and has potential, but it's still mostly a language for mathematicians. There has been some research on AI constructed proofs, which could be the best of both worlds because then the type checker can verify that the AI generated code/proof is indeed correct. Tools like Kani are also a step forward in program correctness.
