Andrej Karpathy once described current AI agents as “slop”.
I think a big reason for that is that most AI memory systems are still optimizing storage instead of retrieval quality.
Most of them work surprisingly well in demos. The agent feels personalized, retrieval feels intelligent, and long-term context appears consistent.
Then the memory store grows.
Old preferences start resurfacing, contradictions accumulate quietly, and low-signal context begins competing with important information. The system technically remembers more over time while behaving less intelligently.
Wrote about why I think the AI memory race is focusing on the wrong layer:
