With the advent of programming languages like Python, Ruby on Rails, etc., there is thinking amongst the developer community that the C language is losing relevance. Strikingly, C is still considered a dominant programming language for system programming as it provides optimized machine instructions for any type of provided input.

It is not the end of programming. It is the end of programming as we know it today. Assembly language programming then put an end to that. Then, development of even higher-level compiled languages like Fortran, COBOL, and their successors C, C++, and Java meant that most programmers no longer wrote assembly code.
