## AI overview

The article argues that web performance optimization should focus on users' real-world experience rather than solely on synthetic tool scores. It explains that Lighthouse is useful for testing and optimization but does not guarantee good field performance: research found that almost half of pages scoring 100 on Lighthouse failed to meet recommended Core Web Vitals thresholds, while some pages with poor Lighthouse scores met those thresholds.

Performance optimization should be about making your users happy, not about making your tools happy. And if we really believe that, we should lead by example.
