Windows is the fault of UNIX? I'm skeptical.

Windows is not a pile of C code, rather C, C++ and .NET.

And nowadays C code is considered legacy, with C#, Rust and constrained C++ as the road to the future.

It's not unfortunate. If it was a bad thing, UNIX wouldn't be so widespread.

>If it was a bad thing, UNIX wouldn't be so widespread.

Strange argument. Javascript is widespread, COBOL was widespread, Windows is widespread, X86 is widespread. Widespread doesn't mean good. UNIX was a disaster, and the whole family of UNIX-like OS spent decades just for mitigate its errors and faults.

I guess we have someone here that enjoys using PHP, JavaScript and Perl.

As a UNIX professional programmer, no. Other than Perl, which I don't use, why would you think that?

Same set of language design qualities and being widespead due to historical accident.
