Jensen Huang said memory management is so important the entire system is called an agent. Most teams are still treating it as a feature.

That gap is where production agents break. Week one memory feels like a feature. You store some context, retrieval works, demos look clean. Month six it is infrastructure. Load-bearing, untouchable, nobody understands what is in it anymore. No audit trail. No correction interface. No way to know what is stale. The teams that get this right stop asking "does the agent remember things" and start asking "can we inspect, correct, and trust what it believes six months from now." Those are two completely different products. Are you building memory as a feature or as infrastructure? And how did you know when it crossed the line?
