What is a serious language? I would call C a serious language. Its running your laptop, your phone, your car, the airplane you took on holiday, the fighter planes that protect your airspace, your washing machine, and if you are unfortunate enough to get seriously ill it will probably be running on the medical equipment that keeps you alive. One of the reasons it is serious is because it is standardized and multiple implementations exist.

I do wonder what other languages you consider serious apart from C. You could use similar examples for a lot of other languages, C isn't the only language used to keep our civilization alive. I did a fair bit of development in C, and developed hard real time systems in VHDL that did involve life & death, but, wouldn't call any language used in the industry generating value as a non serious language...

  I do wonder what other languages you consider serious apart from C. Off the top of my head I thought C++ and Ada. However, you mention VHDL which I agree with and somebody else pointed out Javascript which is also a good point. The Javascript example (along with C++) make the point that serious computer languages are not necessarily great languages. I would argue that Rust is not a serious language (at the moment [1]) because its still young, there is no specification and if anything happens to the one implementation it would be a disaster. Despite C being a null pointer minefield, if someone was to sue a developer the argument could be made that it is an industry standard. In the less likely event that a Rust program hurt somebody what are you going to say?

So also javascript? :)

  Spacex did launch a rocket with an electron interface... In practice, though, V8 is the serious impementation. The interesting thing about C and C++ is that I don't know if any given dev is using Clang, GCC, or MSVC until I ask him. I know a JS dev is using V8.

Brainfuck has a language specification (it's nice and short) https://esolangs.org/wiki/Brainfuck https://esolangs.org/wiki/Brainfuck and a long list of implementations, some even hardware backed. https://esolangs.org/wiki/Brainfuck_implementations https://esolangs.org/wiki/Brainfuck_implementations So if that's the criteria, then brainfuck is a serious language.

  It seems implausible that you don't know the difference between an international standard and a specification document written (of all places) in a wiki, which means you're being purposefully obtuse and don't really have any counter-arguments. If one wants to use a tool in a life-critical system, a system that might be in use for decades they're going to reach for one of the said "serious languages": C, C++, Ada, etc. That list's very short and it includes neither Brainfuck nor Rust for that matter.

    Ok, I picked brainfuck as an - obviously extreme - example of how a language can tick both those boxes and still be not a serious language. I can pick a number of examples of languages that have no international standard and a single implementation and are used in systems that might be in use for decades. Let's take go. A single implementation, it does have a spec, but I'm not aware of an ISO standard. ADA, while having an ISO standard, isn't exactly blessed with many implementations either. Java, while having multiple implementations, is not an ISO standard. The point is: neither of those two datapoints is a particularly useful metric on how "serious" a programming language is and much less even a useful metric on how well it is suited to any given task. Even how mainstream programming languages are is not a useful signal for that. Javascript is very much mainstream, but I hope no one ever will want to program a cars ECU in a JS dialect. Specialized applications are almost by definition the realm of specialized languages.

    It doesn't include JavaScript, either - and yet it's one of the most popular and successful PLs today. Very few people write code for a "life-critical system".

Critical software for planes is written in Ada. C is not safe enough.

  And yet C++ was (in)famously used in the JSF... A less notorious example is Airbus's use of Frama-C.

  That was the idea back in the 80s. Didn't turn out that way, planes, rockets, NASA, still use C just fine, and Ada was not that widely adopted in the end.
