Yes, never learn anything new, never improve, just be a stick in the mud.
Are you saying the C/C++ of today is identical to the C/C++ of yesteryear?
Even over the 4 years I was at university new features were added to these languages. It is still being improved and evolving, it isn't a static 'dead' language that is fixed and never changing. Just like the English language that changes, expands, every year, or humanity itself evolves. The perfect example is C++, it is an evolution, an extension of, K&R C.
