Your computer (especially the semiconductor transistors inside computers), lasers, superconducting magnets and much more are made possible by QM. Classical mechanics and classical EM are no longer areas of study. All modern physicists either study quantum physics or general relativity. Even if they specialize in applied EM, QM can explain more about EM than classical EM.
