I don't imply any judgment (like good/bad) but I tend to suspect the major (not necessarily intentional) reason of all these "second brains" (I use too) to exist in the grand scheme of things is to be a high-quality input for AIs to learn.

Obsidian is offline static markdown files

If offline static markdown exist to be input for AIs to learn, then OK.

But for me, long before Obsidian, they're just notes, because the act of writing them causes you to process them "outbound" which is the same process you need to recall them later.
