Opening: A Conversation That Should Work
Imagine you’ve been chatting with an AI assistant for three months. Last Tuesday, it helped you debug a thorny race condition in your payment service. Two weeks ago, you told it your child is allergic to peanuts. A month ago, you mentioned you’re preparing for a job interview at a fintech company.
Today, you open a new conversation and ask: “Remember that bug we fixed? Could it happen again in the new microservice?”
The model has no idea what you’re talking about.
This is not a failure of intelligence. The model that just forgot your debugging session can write production-grade code, explain quantum field theory, and reason about ethical dilemmas. The failure is something more fundamental: the model has no memory of having lived through anything. Every conversation begins in the same eternal present. Nothing accumulates. Nothing carries forward.
