Not really an argument? The C/C++ ecosystem is so well established that even today you don't have a choice in a lot of contexts.

If that doesn't show the power of a language, I don't know what can. I don't really think the community is toxic or unwelcoming, more like people are too used to ctrl+c ctrl+v their way out of problems. Nothing against that, I'm the same way, but it really is a matter of taking your time with the language. I've honestly learned to applaud most rust fanatics because of this, at least they are passionate about learning athe language inside/out.

Where is C++ the only choice? Gamedev seems like the closest—as far as I know, most AAA games aren’t using C, but I think maybe many are using C# via Unity (I’m not familiar with the gamedev space)? In the embedded world, C still reigns supreme. Maybe in the world of high frequency trading? But these seem to be fewer and fewer and Rust seems increasingly likely to be a contender in these domains.

Game engines are one example, there isn't a robust-enough language other than C++ that has the ability to build some powerful abstractions while also giving you the tools to manage hardware more directly. Note that Unity uses C# as a scripting language, but under the hood the core engine is all in C++.

Under the hood some of that C++ code is now the C# subset used by the Burst compiler.

Drivers, data driven system that have higher performance standards, medical imagery, military components heavily employ Ada mixed with C++ interfaces.

[throwaway894345]

I agree that these things all use C++, but the parent’s claim was that there are areas (industries?) where C++ has no alternatives. Drivers and high performance systems can all make use of C, Rust, Ada, etc as well as C++ depending on requirements.

[spookie]

I'm sorry, but Rust still has ways to go before established industries believe on it enough to drop C/C++. I use C/C++ interchangeably, since extending an existing C codebase won't be a problem. Most aren't willing to go as far as Ada either, the reason why that even in military endeavors, C/C++ is used as a more familiar "face".

I think it's pretty easy to forget the foothold these languages have, and their flexibility. We all have seen the perseverance of COBOL.

[throwaway894345]

My original comment specifically said that older languages have staying power, and that Rust will have to mature a bit to become the language of choice for new projects in these niches. But even still, I wasn’t talking about dropping C++ for Rust—I only mentioned Rust as an alternate option.

[spookie]

No problem, I just don't consider it as an alternative for the aforementioned concerns. Nonetheless, I wasn't trying to point fingers at Rust, more of a pragmatic approach to modernizing a code infrastructure.

I hope Rust does well.

Horse and carriages had a well established ecosystem. We don't use that for moving people and goods anymore.

Being old isn't a superpower. That said, I don't see C++ replaced in certain areas for loooong time.

[spookie]

Yeah, it'll surely fade out given time. It's certainly not a perfect language.
