Did geometry become irrelevant once we stopped caring about field boundaries along the flooding river Nile?
Not everyone uses geometry every day, but engineers do. And we all depend on engineers, so the understanding of geometry is a fundamental underpinning of our entire society. The same can be said of computer science. We don’t all program for a living, but the structure and interpretation of computer programs (the literal structure and interpretation, not the book) is becoming an ever larger factor in how our society functions.
