Fair enough. If you need that level of abstraction to get the job
done, so be it. It's at least a better reason that most of the others
that I have heard. I would comment that levels of abstraction can be
achieved in any language, and that C is just as good any other at doing
so.

You use abstracted libraries everyday.

Although I would have to disagree that C is not tied to the hardware.
That is the whole point of C. That is why C is used over assembly and
why C is considered a universal language. It's usually the first one
ported to any processor.

Saying it is hardware dependent doesn't make sense when C, and the
Linux kernel written in C are used on so many different forms of
hardware.

That can be true, but it is also true of any language, or of project of
substantial size: say 2,000,000+ lines of code. It really depends on
how well it was designed and documented.

Efficiency and guaranteed portability, Diedler. You can't say the same
of Python, Perl, etc - because in order to use them, you have to
compile them from C first.
