Are we all quietly rebuilding memory systems because current AI memory doesn’t actually work long-term?

Summary

The article discusses the common failures of current AI memory solutions in production, such as stale facts, summary drift, and vendor lock-in, suggesting that the real bottleneck is memory governance rather than retrieval.

The more I work with long-running agents, the more it feels like most “AI memory” today is just retrieval with nicer branding. Everything works in demos: * vector DBs * RAG * summaries * context packing * knowledge graphs But after enough real usage, the same problems keep showing up: * stale facts overriding newer ones * summaries drifting from source truth * users changing preferences but old context still winning retrieval * no clean way to inspect why the agent believes something * memory becoming tightly coupled to one vendor/framework At some point every team seems to start building custom correction logic, state management, memory ranking, or invalidation layers on top of the “memory solution” they already adopted. Makes me wonder if the real bottleneck isn’t retrieval anymore, but memory governance: * what gets updated * what gets invalidated * what remains true * what should be forgotten * and whether developers can actually inspect/control it Curious how people here are handling this in production right now. Are existing memory stacks enough for you, or are you also duct-taping custom logic around them?
