It could compile and still have 10,000 logic errors.
Rust is not a major advance over C/C++, only an incremental and quite limited one, which will require decades of rewriting perfectly good code to gain its dubious benefits, in the process introducing numerous other errors.
But don't take my word for it, I'm just the guy who--as usual--is aware right now of facts the rest of you will slowly figure out over the next 20-30 years, after the hype has worn off and you're left with the sad mess that is Rust.
No shallow dismissals please, tell me why you think I'm wrong.
> Rust is not a major advance over C/C++
Rust adds the borrow checker (and especially with non-linear lifetimes it's an implementation like the world has never seen before, not even in Cyclone). That alone raises it leaps above both C and C++.
But even without it, it still has a Hindley Milner type system (which most people considered superior to multiple inheritance), it has Sync/Send traits, the concept of UnwindSafe, proper destructive moves and affineish types, proper sum types and matching, sane iterators, lack of UB on uninit/overflow/etc, a sane module system, hygienic macros, and that's just the things I was able to pull of the top of my head right now.
Not to mention, the design of its stdlib is absolutely lovely compared to what C++'s stdlib has become, and it focuses on correctness much more than most other popular languages.

Tell me why you think you're right.
Hint: you're wrong.

No, not really. It's an incremental improvement at best.
In time you will learn about all of the faults and flaws in Rust, after you've suffered the pain of trying to rewrite the entire universe in it just to fix one single class of problem you are obsessed about--inevitably introducing many new bugs in the process, because that always comes with the territory.
I know exactly what the successor to C/C++ looks like, and it's not Rust.

Blah blah blah. Most of that is just added runtime complexity that I could add to C if I wanted, but why would I? None of that crap is needed. Most of it is wankery, the sort of stuff that 20-somethings salivate over but which in the end is meaningless, just change for the sake of change.

Ada is the language to emulate, not Rust or C++. Again, the actual successor to C/C++ looks nothing like Rust.

Good thing Rust doesn't just fix that one class of problems, but also provides better tooling to fix other classes too. Classes of problems that could be fixed with the other features of Rust mentioned later like the Hind...
> Blah blah blah. Most of that is just added runtime complexity that I could add to C if I wanted, but why would I?
...the vast majority of these features don't even run at compile time. Some of them can't even be implemented in C. For starters, show me an example of a Hindley Milner type system implemented for C (how can someone improve a strictly compile time feature, static typing, with a runtime implementation is beyond me). Or proper destructive moves in C or C++.

Good thing Rust also takes from Ada.

Wow, what a magical language! [ waves hands vigorously ] will fix all the problems which are inevitably introduced by auto-porting from one language to another, or by manually rewriting everything from scratch. Rust doesn't obey the same laws of the software universe as other languages, it seems.
Rust will even automatically rewrite itself to use its own special idioms rather than whatever loser idioms it has sadly inherited from the C/C++ code which the developer, in his infinite benevolence, has decided to lift from its Dark Ages level of inadequacy to Modern Language Standards, with nothing but joy and happiness as the result. Miraculous.
Or is this a "just use magic AI to do it all bro", type situation?
In the latter case, why don't I just use the magic AI to auto-magically solve my C/C++ problems, rather than rewrite the entire universe from scratch? You know, like Google claims to have done for Chromium C++ sources in this very news article?

What part of "I don't care about any of that crap" aren't you grasping?
This is the type of shit noobs are always wringing their hands about, as they want new toys to play with and/or maximum guardrails to cover for their ineptitude. Which is exactly why Google wants these kind of things, as their median developer is some kid fresh out of college. They want a magic language that will protect the idiot programmer from himself and eliminate all errors, so that any trained monkey can use it, as they plan to train actual monkeys to do this if they can somehow get away with it.
Well, that isn't Rust. Not even close. It's just the next horror show masquerading as a "fix."

It could. Switch that to C or C++ and the amount of logic bugs is likely going to triple.

"Nothing ever happens." I guess you could consider borrow checking, an actual module system, type classes, enum variants, compiler-integrated macros, async/await, etc. to be just small increments. (Theoretically, you can reimplement most of this in C++, like std::variant, but they don't integrate well into the language - having to declare a type just to use std::visit is certainly not as simple as using match).

"Introducing numerous other errors"? Would be interesting to see an citation on that. From what I've seen, these "new errors" were already present in the original "perfectly good code", except the original also had instances of undefined behavior and logic errors from poor type modeling.

Why would anyone other than your friends take your word? You could have substantiate your claims with actual evidence.

Which already did. Nowadays, I see more posts about Zig and Fil-C.
>[...] left with the sad mess that is Rust.
I went to read your comment history to see if you elaborated on this "sad mess" of Rust, but you didn't. How about you do it here?
The sentiment of "if it compiles it probably works" for languages like Rust and Haskell is there for a good reason.
