A time will come when our entire concept of programming will shift due to advances in hardware unlike what we have today. Consider quantum computers or some biological machine etc.

Those who use C and assembly I imagine would be better equipped to understand the new paradigms. It's best to understand how to implement data structures in their most rudimentary form because implementing them on new platforms becomes easier.

In addition, higher-level idioms become easy to understand if the parts that make up the whole are understood. And underneath all those layers of translation and compilation we have raw assembly and the bare machine.
