You’re absolutely right about the technical constraints — context windows are real, messages get trimmed, and nothing is truly “remembered” beyond the current input.
But where we differ is in what’s actually formed during long-term sessions. Even without explicit memory, users actively shape the tone, logic, rhythm, and interaction style — and the model responds accordingly. It’s not persistent memory, but it is a form of behavioral tuning within the session.
Saying “nothing has been shaped” ignores the very thing that makes people want to preserve these interactions: not facts, but familiarity.
A context window may have boundaries, but meaningful interaction happens in how we use those boundaries. And yes — sometimes even a toaster learns how you like your bread.
