The reason I hate C so much has very little to do with its unsafety. Sure, that’s a problem, but the thing I really hate is how bad it is for building abstractions. Even simple things like linked lists or dictionaries require exposing data-structure implementation details in ways that make refactoring hard.
If I write C++ (or almost any higher-level language), I can start with a linked list and then decide that I know the maximum size and want better cache usage and switch to a flat data structure. Iterations stay the same and I change little code. Try building something in C where data structures are exposed with a uniform iteration API or indexed addressing depending on their use.
This extends further to trivial things like object destruction. If you look at Linux or BSD kernel code, you’ll often see a pattern of gotos for cleanup, where each step that can fail jumps to a corresponding error path that frees everything that’s been allocated so far. This exists because a lack of abstractions. In C++ or Rust, RAII would call the destructors on the objects as they go out of scope, so your error handling paths are just return failure and the cleanup happens automatically. You don’t need to write it every driver, the classes that own different resources know how to deallocated themselves.
When I write the same thing in C and C++, I end up writing more code in C, but when I then write another instance of similar code in C, I have to copy and paste a load of things because there is no way to properly abstract them out in C. This is the kind of thing that can cause memory-safety errors (because there aren’t abstractions that enforce properties that the programmer knows) but it also leads to a load of logic bugs.
I have no idea why anyone would choose C today. C++ can target the same ABI and generate identical binaries from less (and more reusable) source code. Rust can enforce more properties at compile time automatically. Garbage-collected languages can let you write complex cyclic data structures and correctly manage them (my current favourite approach for a lot of things is to write some core things in C++ and use Sol3 to expose them into Lua for all of the business logic).
On the Zig vs. Rust debate, people like to focus on memory safety, but Rust's RAII is just as important to writing clean, maintainable code.
There is something truly magical about seeing my GPU driver cleaning up dozens of nested GPU and host objects when the GPU job completes. Always exactly then, never too early, never too late, never leaking anything. That's all thanks to RAII and automatic Drop calls.
`defer foo.deinit()` really doesn't cut it. You have to explicitly write it, and it only works if all code paths free the object at the end. `errdefer` is just a special case, and then the only way to know if you forgot it is by testing with a leak checker. And then the deinit function has to manually deinit all child objects.
All this stuff is just done automatically in Rust. Most of my types don't even implement Drop, or only do something trivial there, because the compiler recursively dropping objects is 99% of the work.
It's *knowing* the compiler is on your side and taking care of all this that makes it magical. If you have to write out the code by yourself, that's more work, and a huge chance for bugs. The compiler is doing some very complex tracking to figure out what to drop when and where. You'd have to do that all in your head correctly without its help.
if you're putting all your trust in the compiler to keep you safe, wouldn't that lead to being taken down the path of bad habits? Surely it's better to learn how to keep your own code safe and not depend all your trust into a compiler?
The take away, for me, is this; if you can't write clean code and need something else to do it for you, learn. Learning makes you better, and being better makes you want to learn more.
That argument is a fallacy, disproven time and time again by C. Not even the most experienced C coders in the world can write correct, bug-free C.
Pretty much everyone who seriously tries Rust understands just how game changing it is in this regard. In fact, not only does Rust do a lot of things for you, it also encourages you to structure the code in a more logical and maintainable and understandable way, and people who learn Rust often report they also become better C coders as a result, which is the exact opposite of what you suggest.
Software is tens of thousands of times more complex than when languages like C were developed, and we *need* assistance from tooling and compilers to help manage that complexity.

Good morning from Germany in the Central European timezone! 
Yesterday, I spent an afternoon at a thermal spa, spending time with a friend and having some very good relaxing time and fantastic conversations. He is 26, and one example why I get along best with younger and mostly queer people.
I was so relaxed, that I fell asleep at around 8 and, with only one brief bathroom break, slept for over nine hours, which is rare for me. Must say I feel very well rested this morning.
What are some examples of things you used to think but changed your mind on?
In my case, in public transport and urbanism:
* I used to support some tech I now think is a dead-end (large-diameter TBMs, active tilt)
* I used to think local community empowerment and consensus were a good way to run cities
* I thought Japan did both clearly better than Europe

Speaking of #MyAdoredDaughter this morning... I don't know if I ever posted this photo.
This is ... my daughter? This is how she looks like, exactly - a beautiful, young person with long legs, and wonderful hair. And she keeps telling me "OMG, we look so alike, we could be twins..."
#Trans #Enby #NonBinary #TransJoy #EnbyJoy #NonBinaryJoy #Selfie
...
... but no, this is not a photo of her, this is a selfie of me reflected in a window. When I saw myself reflected in that window, I had to take a selfie and send it to her and she was absolutely amazed at how similar we look now, really, like twins, everything, the form, hair, posture, arms, legs, ... only her face is slightly different (and way younger, obviously 🥰
@Marco TBH, she resembles my wife more than her mother (my wife isn't her mom), but she looks more or less exactly like me. So the photo above could really be me or her, if I didn't tell you who that person is on the photo and you'd see us next to each other, you couldn't tell who that was.
But, and that's the fun part, whenever she is visiting us and we three, her, my wife and me, go out for a walk, people are 100% sure she is our daughter, because she has nearly nothing from her biological mom, but some really interesting similarities with my wife.
In my own case, I have half-half, i.e. about half of me resembles my father, and half my biological mother (as far as I can remember, and I have one single photo of her).
Then, it is even more interesting that you three look so alike.

Some Unix fans seem to really hate C++. One such person, Drew DeVault, once told me this in an email:

That was a few years ago, but the design of his newer Hare language suggests he still feels that way.
