I think the schema is already there. You can read and understand it, right? So its has more structure for you than just entropy.

How to capitalize this is indeed a harder question. My mind gravitates more towards something like GPT3. If you fed it all your memories (expensive, I know) and gave it a prompt of "I was thinking about a funny gif with a dog and a mug in a room on fire", it'd for sure get you the this_is_fine.jpg. But the answer is not quite what I typically see myself wanting. Instead, I want to navigate this graph (the understanding necessary to make the connection from the prompt to the jpg in the first place) myself, and see what's interesting and non-obvious there. That's what I interpret as "being able to talk with your zettelkasten".
