Modern systems language?

(Spoiler: There isn't one)

C and Sepples are more trouble than they're worth. Pascal is basically a better-and-yet-somehow-worse version of C. Ada is basically a better-and-yet-many-times-more-verbose version of C++.

I don't think I need to say what C++ is.

Go will never be good. Python will never be good.

Is there a language that's good that I don't know about?

The real problem with C is that retards teach naive students to use malloc, but don't teach them how and why to avoid memory allocation whenever possible.
