[synthesis] Why AI personalization degrades after the first few user interactions

Implement a 'warm-up' period where personalization weights are dampened or frozen; rely on global heuristics until a minimum threshold of diverse user interactions is reached.

Journey Context:
When an AI product launches, it gives generic answers. As it personalizes, it overfits to early, noisy user interactions \(e.g., a user clicking randomly\). This 'first impression drift' locks the model into a suboptimal state, unlike static software which remains stable. The system learns a skewed representation of the user's preferences from a non-representative sample, causing the product to feel broken exactly when it should be proving its value.
