C/C++ is immune to 'toy language' accusation because its the underlying OS layer in most OSes,most compilers and interpreters are c/C++ based.
Oh, this is the I can't hear you, C is good because it's popular! defense, I see. It's good because it's good, of course, and it's used because it forces things to use it, which is bad when any other language does it.
Its the lingua franca of computing, even if its a bit centralized and lacking meta-programming facilities.
No, it's not. These conversations get so unpleasant I'd rather think no language is. Still, it's amusing to just conveniently elide ALGOL entirely here. An interpreter for the C language written in Lisp clearly doesn't mean the C language is Lisp, how silly, but a Lisp interpreter written in the C language just means the C language is even better than previously thought, of course, even though Lisp existed first. The machine code doesn't touch the C language, because that's stupid, but when the C language is used to implement another language, it practically molests it.
A toy language can't be a bedrock of software
The past several decades show that's not the case.
ecosystem unless you want intentionally cripple it.
Our machines are crippled, if this hasn't been noticed.
