My remark was contextual. I am not saying there is no value in in practical implementation. Obviously, there is enormous value! But these are secondary to what computer science is about, so if your concept of computer science and programming are machine-centric, then this is by definition not a computer science POV. If you take the machine to be the primary object of computer science, then you are either taking a computer engineering position, or you gravely misunderstand the essence of programming.
