The author argues the "AI second brain" idea is slightly off: the problem isn't storage but that most AI tools only see what's in front of them. Feeding in one batch of customer interviews yields a decent summary; a newer batch yields another — but the deltas and recurring signals between them get lost.

In CREAO he experiments with a workflow that feeds older and newer material together and asks the AI to compare them rather than treat each batch as a fresh question, so answers carry historical context. Takeaway: AI memory shouldn't retain every file, just enough relevant context to notice what's changing over time.
