By studying a number of examples, we have come to the conclusion that programs in less expressive languages exhibit repeated occurrences of programming patterns, and that this pattern-oriented style is detrimental to the programming process.
The C-only train has left the station. Few departments teach surveys of programming languages anymore, and I don’t know of any department that teaches a required course in history of computing. I worry about what this means for our discipline.
Are we really going to tell students that the peak of human expressibility for computation was in 1973? That all programming language research from here on out is wasted energy? That simplicity is all that we can ever hope for, and correctness and consistency just aren’t worth working on?
Are we forever stuck with 30+ year old ideas and don’t even teach that anything else is possible?
