Craft and expertise are worth a lot, but so are the facts of computer science and so are people wanting to debate and try new things some mistakes repeat (and computing seems to repeat it's self so many times.), But those zoomers might have the theory fresher in their minds and they might have studied something you have not or did not know.
If what you learned in university was plain wrong that does not sound good because computer science has eternal truths to it, If an architect said everything he learned in university was wrong I would be very worried and not trust his judgement because he should have learned facts not just theories of practice. If he only learned theories of practice I would be worried, if he learned both theories of practice and science and starts to disagree with the science I would be worried.
