All programming languages suck in their own way. Naturally people want to create languages that suck a bit less for their particular problem.

Go was created because compile times in C++ are ridiculously long. Rust was created to prevent common memory bugs without sacrificing runtime performance.

C and Python are still widely popular. It’s rare these days that a new language completely displaces an old one, so don’t worry about being left behind by learning an ”old” language.

Other popular languages are C++, Java, C# and JavaScript.
