> Modern C++ isn't really safe.

Can we cut it out with the hyperbole? Using "It Isn't Really Safe Unless It Is Written In My Favourite Niche Language" as an argument is .. well ... ridiculous. You can extend that argument to any practical programming language.

So ... Rust ... "Isn't Really Safe" because you can get into a point where memory is corrupted, where your application deadlocks, or threads starve, etc.

Haskell ... "Isn't Really Safe" because it is not possible to formally verify the logic.

Etc, ad infinitum ...

Maybe go for "Not As Safe As". After all, I don't even like C++ (see my comment history), but it's certainly possible (and not very hard) to get about 90% of Rust safety in C++.

Safety is not a binary, it's on a spectrum. Saying that a language is either safe or unsafe implies that the "safe" language is actually safe while the "unsafe" language is completely deadly. That's certainly not true.

i dare you to find memory corruption in safe rust that isn't already on an issue tracker.

tell that to the people who got owned by https://googleprojectzero.blogspot.com/2021/12/a-deep-dive-i... , most likely human rights activists targeted by less-than-savory regimes. memory corruption bugs are so frequent that it is possible for nso group to sell to pretty much any regime, and not forced to be classified as top secret information.

can't you just mess around with /proc/self/mem :)

That one was already reported to the tracker :)

https://github.com/rust-lang/rust/issues/32670

(To be clear, I’m not saying that there’s no issues that aren’t in the tracker yet. But there are a bunch of them that are. More will absolutely be found as time goes on, that’s just how these things are.)

Thanks, that was an amusing read!
