Persistent memory changes how people interact with AI — here's what I'm observing

I run a small AI companion platform and wanted to share some interesting behavioral data from users who've been using persistent cross-session memory for 2-3 months now. Some patterns I didn't expect: "Deep single-thread" users dominate. 56% of our most active users put 70%+ of their messages into a single conversation thread. They're not creating multiple characters or scenarios - they're deepening one relationship. This totally contradicts the assumption that users are "scenario hoppers." Memory recall triggers emotional responses.
