In the field of supporting AI adoption at companies, I keep hearing the same complaint. "I keep correcting the same mistake." "I explain carefully and nothing changes." "Maybe my prompt is the problem."

At first, everyone is excited. The AI drafts an email, summarizes a meeting, runs through research faster than they could. This is going to change how we work. Then they keep using it, and every time they end up retouching the same parts. They make their instructions more careful, they write rules, nothing changes. The conclusion they slide toward is: "Maybe I'm not communicating well enough."

That feeling is real. But it is not a communication problem. It is a structural one.

The mechanism: "yesterday" doesn't reach the AI

The fact that AI doesn't carry memory across sessions is not a bug. It is by design.
