Having done a bachelor/master in CS and taught a coding bootcamp, I only believe this to be partially true. It depends on what work you want to do as a programmer. For example, if you want to become a web dev at an average organization, then compiler construction knowledge isn't the most optimized way to spend your time. Yes, it'll add to your general programming knowledge, but it's better to spend the time to directly learn JavaScript, how to setup a project structure, devops tools like Docker and so on.

People that claim that such things aren't timeless are missing the fact that once you've seen enough tools that your underlying knowledge becomes deeper (and therefore timeless) as well.

What will happen though is that when you're doing your job is that you'll begin to notice that you miss certain fundamentals. At such point you know what you're missing, and you can immediately do targeted learning without doing a whole bachelor for it.

This whole story does pressupose that you know aprior what kind of developer you want to be, which is not an easy feat since it's a bit a chicken/egg problem (i.e. you need to know programming and have seen different flavors in order to better know what you want to become).
