[synthesis] The latency/quality tradeoff in AI inverts traditional software expectations

Intentionally add streaming and 'thinking' indicators to AI responses, and avoid optimizing for zero-latency if it requires downgrading model capability, as users tolerate slower AI if they perceive it as 'thinking harder.'

Journey Context:
In traditional software, faster is always better. Latency is purely a technical metric. In AI, there is a psychological inversion: users often associate slightly slower, streamed responses with higher quality reasoning \('it's thinking'\). If an AI responds instantly with a complex answer, users often distrust it \(feels like a cached search\) or find the answer superficial. Optimizing purely for latency \(e.g., using a smaller, faster model\) can actually reduce perceived value, whereas streaming tokens to mask generation time improves the UX without degrading quality.
