If it was "learning about computer internals" that would be one thing. Most of it is closer to "learning which kernel version randomly works with your hardware" and then rewriting your tiling window manager configuration file because the old format isn't supported anymore. You could spend that time studying an EE textbook instead and get more widely applicable knowledge.

Whatever makes you happy is fine, but beware putting yourself on a high horse with statements like "if you don't see value in learning...".
