If that’s so trivial to trigger, people would be doing so everywhere. Have you seen it in the wild or heard of anyone doing so?

Yes, the problems rust is solving are already solved under different constraints. This is not a spicy take.

The world isn’t clamoring to turn a go app into rust specifically for the memory safety they both enjoy.

Systems applications are still almost exclusively written in C & C++, and they absolutely do run into memory bugs. All the time. I work with C almost exclusively for my day job (with shell and rust interspersed), and while tried and tested C programs have far fewer memory bugs than when they were first made, that means the bugs you do find are by their nature more painful to diagnose. Eliminating a whole class of problems in-language is absolutely worth the hype.

Go, Java, and Nim (in most cases) are all memory safe but are generally slower than C or C++ due to the ways they achieve memory safety.

Rust’s memory safety approach is zero-cost performance wise, which makes it practical for low level, high throughput, and low latency applications.

What I mean is that even if you use GC languages like Java or Go you will still encounter annoying bugs. I’m not saying that memory safety isn’t important.

Once you get the hang of rust you don’t ever need to ask it to do unsafe things. It’s not really any faster to do things unsafe

That flag exists, it’s called unsafe for if you need to tell the borrow checker to trust you or unwrap if you don’t want to deal with handling errors on most ADTs.

You can always cast anything to an unmanaged pointer type and use it in unsafe code.

This is definitely into the territory of misinformation.

I don’t write Rust, but lots of programs I use do and, as I said, they seem to crash about as much as any other compiled language tools I use are written in

I already addressed this before. Regular crashes are almost always (I can’t remember any exceptions) due to panics or aborts chosen by the user - especially due to unwraps. Using that to equate Rust programs’ stability to ‘any other compiled language tools I use are written in’ is very disingenuous - because it’s just as easy to handle those errors and prevent a crash at all.

If not doing segfaults is what makes a language “safe,” then it seems to me most modern languages are as safe as Rust

You are unnecessarily conflating issues here. ‘Most modern languages’ are not a replacement for what C, C++ and Rust can do. Go most famously had to retract their ‘systems programming language’ tag, for example. If a GC language meets your requirements - then by all means, use it. But it’s not without reason that many companies have rewritten even their web backends in Rust. Memory safety without GC is a very big feature that a lot of professionals care about. It’s not something to dismiss as trivial.

And while at it, you neglecting what segfaults represent. It’s just a benign example of memory safety bug. It’s benign because it gets caught causes the program to crash. There are a whole lot of them that causes the program to continue running - causing serious vulnerabilities. This is why even the US government and agencies recommend memory safety languages and especially Rust if performance and other limitations matter.

If we include crashes, then as I said, I see Rust programs crashing about as much as any other proglang.

I really don’t want to repeat the reason twice in a single comment and 3 times including in my previous comment. But the only way you are going to make Rust crash as much as ‘any other prolang’ is to neglect idiomatic Rust. That isn’t surprising because crashing anything is possible if that’s your intention.
