If you arent teaching the modern tools then you arent teaching the "marketable skills to get a job" which is increasingly the focus of education. Nobody cares about underlying principals anymore.
Somebody needs to care, or we end up with a society that doesn't know how things work at a fundamental level, which is also the bases for major innovations. Imagine LLMs coming into existence without anyone understanding the principals of linear algebra. Imagine making advances in physics or chemistry without underlying principles.
