AI Memory Flaw Exposes Time Gap

The right fix is less about bigger vector stores and more about memory governance. Once you model time, you also have to decide what should persist, what should decay, and what should be rewritten.

• –Without temporal policy, memory turns into a retrieval lottery: stale but similar items can outrank what is actually current.
• –Good memory needs separate handling for ephemeral context, durable preferences, and evolving commitments.
• –Long-running agents need provenance and conflict resolution, or they become efficient stale-context machines.
• –Recent work on latent state persistence and temporal coherence shows the field is already turning this complaint into benchmarks.
• –For builders, the real question is no longer "can it recall?" but "what changed, when, and why?"
