What AI “remembers” about you is privacy’s next frontier

Google launched Personal Intelligence this month, letting Gemini use Gmail, Photos, Search, and YouTube history for personalization.

The key issue is memory architecture: segmentation, provenance tracking, user edit/delete controls, and privacy-preserving evaluation.
