I think the key thing is that Spotlight is now creating a... knowledge graph? of everything on your device for Siri's consideration. That's potentially very useful.

I suspect it is Kuzu in the backend. I had called it out earlier this year in my article. ".. WWDC 2026 or 2027 introduces any “contextual intelligence” features in Siri that require cross-app relationship reasoning."https://medium.com/data-science-collective/i-analyzed-163k-l...

The "knowledge graph" has been there for a long long time....

I think it’s just storing embeddings now.
