It really has no legitimate reason for our attention. It addresses no actual problem not better addressed elsewhere. Even Zig is better justified, but isn't.

Hare is meant to replace C in the creator's affections. But any language meant to be adopted by C coders is doomed: remaining C coders are defined by having seen a thousand languages go by, and passed on all of them.

Both C++ and Rust address C shortcomings with powerful advances in productivity. Weak-sauce C updates are at best a distraction, at worst compound its problems by siphoning off coders from alternatives. The people they are for don't want them, and new programmers are much better off with actually-better languages.

I think that's an overstatement that kinda dilutes your general point.

Maybe with “thousands” part. But there definitely have been tens and, depending on how you would count them, hundreds of languages which were expressly designed to be a “better system language than C”. All these C++, Objective C, D and lots and lots of other languages were designed as “C replacements”. Yet they all failed at replacing C.

Which means that remaining C programmers need something extremely compelling to switch. Rust offers that (although it's not clear if that theoretical offer is nice enough in practice), Swift does that, too (although it's an Apple language thus highly unlikely to ever be widely used outside of Apple's ecosystem). Hare? Nope.

Bunch of cosmetic improvements without a clear explanation why it's better than C or hypothetical BoringC/FriendlyC.

This might be a slight exaggeration, but I think it is the right statement. Thanks, I'll remember this, it's well said.

I think many people who still use C do so for the same very simple reason I do: it works, has a reasonable community (many libraries) and, most importantly, code written today has a high chance of continuing to work unmodified far into the future. C is the only language which delivers all three, even though that last part is going down the drain these days because of continued exploitation of undefined behaviour. No matter what I find exactly no enjoyment being on a permanent treadmill having to jiffy my code around so that it works again with whatever "awesomeness" the language designers decided to change in the last few months or, even worse, to find that the language has been abandoned and now my code needs a full rewrite in something else. Is this really so bad ?

No, C programmers are not degenerate psychologically challenged moronic narcissists who work day and night just to deliver security issues and bugs to you. Could we be civil and stop looking down on people who code in C, please ?

I think you misunderstood my reply entirely. I think the post I quoted was valid in the sense of - C programmers have seen enough fads coming by and passing, and yet - as you say - C still works. Not in the sense "they're dumb and cannot adjust".

Thanks for clarifying and sorry about my misunderstanding.

I think you're taking this the wrong way - the point is that C programmers value the fact that C someone wrote 30+ years ago is still useful C far more than they value any new language feature that's not in C2x (or often, C99 or C90).

As a consequence of this, the bar for "new language that will attract people away from C" is very, very high. The natural instinct of the remaining people who prefer C when faced with a new language is not "oh, that feature is awesome and I will switch language to get it", but "will that language still be usable in N decades time? Can I implement the feature usably in a C library?".

If you do value that long-term stability over the language features, then a new language aiming to attract you has a big hill to climb - being new, it can't point to 30+ years of history like C can, and so how can it convince you that code written for the language as it exists today will still be useful code in 30 years time?

After all, we've established that that's a big chunk of why you use C - because you've seen so many attractive languages come and go in C's lifetime, and you don't want to start a project today that'll be impossible to compile (let alone use) in a decade. And that's a perfectly good reason to prefer C - it's the same reason that a lot of physicists prefer Fortran, because they want their code to still work for cross-checking results decades after a 20 year experiment comes to an end - but it does make it hard for a new language to attract you away from C.
