I feel old too, reading this same argument today. I joined this industry in early 2010 and people were saying the same things about frontend stacks. Back then, I believed that the people making this argument were onto something, as it felt overly complicated to me as a beginner. At this point it feels more likely that the people making this argument don't have any kind of experience in frontend development that span multiple teams collaborating on the same UI. In the backend this was "solved" through mocroservices. In the frontend you're gonna be in a world of pain unless you're using one of the popular spa frameworks. Well, you're probably still gonna be in pain. It'd just be worse if you didn't use the framework.
