Computer science is about the science of computing not the latest trends in software development. Those don't change the fundamentals of computer science.
I mean I guess but CS is also the track you get put on if you want to be a SWE. I would make an even stronger statement that within a rounding error 0% of the students in a given CS course will go on to be computer scientists. So while what you're saying is literally true there is a real disconnect between what students in CS programs want to learn and the skills they want to acquire and what is being taught. The parent is very reasonably picking up on that.
This isn't really limited to CS programs either, something is deeply wrong with the system when college grads are only marginally more prepared to enter their chosen field than HS grads. One of my friends does work building cutting edge sensors for scientific equipment— literally the ideal case for an academic curriculum. They not two months ago rejected an ivy ECE major in favor of a guy with no degree but who builds custom toy drones as a hobby.
