Yes I already had similar thoughts.

Would be very convenient to keep automating it and at a certain size of notes/zettels the AI could help to come up with suggestions you want to link new notes/zettels to.
Especially since sometimes we would forget how we named the note/zettel a few years ago.
Sure, hashtags and other indexing is possible but often creates more of a mess than it helps^^.

The main reason I do not want it for myself is, that I use my devices and especially my setup "as offline as possible" if you know what I mean.
So an AI would make me dependent on internet connection which I always try to avoid if possible.
