I was concerned about that too, but I believe Macs at least guarantee tag syncing between other Macs. I may experiment with putting tags on the first line, but for now, I’ll have to rely on folders and my summarizations.

I may just settle for org-mode if I end up doing a PhD because, as the top commenters pointed out, Zettelkasten is meant to be a system to link ideas within the humanities.

However, I’m focused on my professional life right now. Most of my reading material is quantitative, so my current system is fine.
