Thread and/or concurrency abstraction (and/or other abstractions provided by a language) allows information/knowledge about how to deal with the abstraction (option or default) to be provided to the compile behind the scenes. aka when coding a program, when was the last time coded a stack/heap to do a function call with parameters instead of using a language provided way of calling a function with parameters? This just seems weird with C because C language was designed to map as closely to hardware instructions as possible (hence why quite a lot of things in C are 'undefined' / dependent on platform used.) Most modern languages are designed so that hardware issues are not a programmer's thing, but a compiler implementor's thing. Allows for much more sophisticated hardware without burdening the non-systems programmer.
