Rust is much easier to learn due to C/C++ books all being paid (even cmake wants you to buy their book) whereas Rust documentation is free. I bet more and more people are choosing to learn Rust over C/C++ for this reason, and the number of C/C++ devs will be decreasing.

what a weird take to me... C has DECADES of high quality teaching material in form of books, university courses, plenty of which is freely available with a bit of searching. And, if we discount the fact that "buying" a book is such a big hurdle, even more high quality academic text books and papers to boost; anything from embedded on the weirdest platforms, basic parsing, writing compilers, language design, high performance computing, teaching of algorithms, data structures, distributed systems, whatever! edit: I even forgot to name operating system design plus game programming ; and of course accompanying libraries, compilers & build systems to cover all of those areas and use cases! edit2: networking, signal processing, automotive, learning about industry protocols and devices of any sort... if you explore computer science using C as your main language you are in the biggest candy store in the world with regards to what it is you want to learn about or do or implement...

  > anything from embedded on the weirdest platforms, basic parsing, writing compilers, language design, high performance computing, teaching of algorithms, data structures, distributed systems, whatever All that is language-agnostic and doesn’t necessarily have anything to do with C.
  - cynical_german 2y ago
    Yes, but there is material covering all of those aspects with implementations in C plus libraries plus ecosystem support! From teaching material to real world reference implementations to look at and modify and learn from. And C maps so directly to so many concepts; it's easy to pick up any of those topics with C; and it being so loose makes it even perfect to explore many of those areas to begin with, since very quickly you're not fighting the language to let you do things.
    - koakuma-chan 2y ago
      People may learn from material that uses C for illustration purposes, but that won’t prompt them to write their own C. And don’t even mention ecosystem support in C/C++ where developers are notorious for reimplementing everything on their own because there is no package manager.

        "rust import csv-parser" "you've installed 89 packages" why is my executable 20 mb, not as performant as a 50 kb C file & doesn't build a year later if I try to build with 89 new versions of those packages obligatory xkcd reference: https://imgs.xkcd.com/comics/dependency_2x.png https://imgs.xkcd.com/comics/dependency_2x.png this is what package managers lead to
        koakuma-chan 2y ago
        You are greatly exaggerating the numbers, and Rust and its ecosystem are known for being stable. Are you saying everyone should write their own csv parser? Also it’s highly likely that an existing CSV library would be optimized, unlike whatever you wrote ad-hoc, so your performance argument doesn’t hold.
        cynical_german 2y ago
        I'm saying package managers automate dependency hell and software is and will be less stable & more bloated as a consequence. And one should know how to write a csv parser and yes, even consider writing one if there are obvious custom restraints and it's an important part of one's project. (and yes, numbers were exaggerated; I picked something trivial like a csv parser pulling in 89 packages for effect; the underlying principle sadly holds true)
        koakuma-chan 2y ago
        Anyone can read a file, split it by newline and split it by comma, but what if values contain newlines or commas? How do you unescape? What about other edge cases? In Rust an existing library would handle all that, and you would also get structure mapping, type coercion, validation etc for free.
- koakuma-chan 2y ago
  > C has DECADES of high quality teaching material in form of books, university courses, plenty of which is freely available with a bit of searching. Which means all that high quality teaching material is DECADES old. Rust development is centralised and therefore the docs are always up-to-date, unlike C/C++ which is a big big mess.
  - cynical_german 2y ago
    Oh my... Are you serious? I'm almost triggered by this. A book about algorithms or data structures from 20 years ago has nothing more to teach? 3D game engine design from 20 years ago has nothing more to teach? No point in looking at the source code of Quake, reading k&r, and Knuth's TAOCP Volume 1 was published in 1968 so it's obviously irrelevant garbage! I could spurr into an essay of what kind of lack of understanding you just portrayed about the world, but I won't.... I won't...
    - koakuma-chan 2y ago
      We’re talking about C/C++, not algorithms or data structures.
      - jpc0 2y ago
        How you implement algorithms and data structures in C++/rust is semantics at best. The imperative shell of those languages are identical semantically right down to the memory model.
        koakuma-chan 2y ago
        Right, that's why a 20 year old book on algorithms and data structures is not necessarily outdated, but a 20 year old book on C/C++ most certainly is.
        ryao 2y ago
        My copy of The C++ Programming Language for C++98 is still useful today, as is copy of The C Programming Language for C89. The idea that these books are no longer useful is absurd. Modern compilers still support those versions and the new versions are largely extensions of the old (although C++11 changed some standard library definitions). The only way you could think this is if you have zero knowledge of these languages.

  > edit2: networking, signal processing, automotive, learning about industry protocols and devices of any sort... I admit there is many great products that are written in C that aren’t going anywhere any time soon, notably SQLite, but there is no reason to write new software in C or C++.
  - cynical_german 2y ago
    I do, and will, the industry does and will, for at least a few more decades. And I even enjoy doing so (with C; C++ is more forced upon me, but that'll be the case for some time to come)
    - koakuma-chan 2y ago
      That’s what I’m saying. By a few decades you and most of those alleged 7 million C/C++ developers will retire and there won’t be anyone to replace them because everyone will be using Rust or Zig or Go.
      - quibono 2y ago
        Very strong statement, one I don't really believe
        koakuma-chan 2y ago
        That’s what happened to COBOL, right?
        ryao 2y ago
        In COBOL’s case, nobody really wanted to write software in it in the first place. People used assembly or FORTRAN at the time. MBAs wanted a language corporate secretaries could use, so they made COBOL. It failed at its main purpose, but since IBM pushed it for business processing, people were coerced into writing software with it since if they did not use it, they would not have a job. As the industry developed, they stopped finding new people that they could coerce into using it and the old people started retiring/dying. Unlike COBOL adoption, C and C++ adoption occurred because software engineers wanted to use them due to merit.
uecker 2y ago
Probably not. Many people prefer C/C++ to Rust, which has its own fair share of problems.
- koakuma-chan 2y ago
  Two people is many people. The general trend I see is that Rust is exploding in adoption.
  - uecker 2y ago
    It is, but it is still tiny compared to C/C++. And many people also do not like it.
    - koakuma-chan 2y ago
      There are two categories of people who don’t like Rust: 1. C/C++ developers who are used to C/C++ and don’t want to learn Rust. 2. Go developers who claim Rust is too difficult and unreadable. Which one is you?
      - ryao 2y ago
        I know a guy who used to love Rust and his cannot stand it. The hype wore off in his case.
        koakuma-chan 2y ago
        Does he prefer fighting libtool, make, cmake, configure, automake, autoconf and autoreconf just to add a couple libraries into his project? When I tried to use C, I wrote 10 lines of code and spent hours trying to make all that shit work. It makes me laugh when people say Rust is complicated.
        ryao 2y ago
        It really is not that complicated. You just use -llibrary when linking and it links.
