The blog post discusses the author's changed perspective on prefetching in web development, inspired by the Speculation Rules API. Initially critical of prefetching due to concerns about bandwidth and resource waste, the author finds it more reasonable with the conservative eagerness setting, which triggers prefetching only when users show intent to click. This method respects user settings like battery and data saver modes and allows developers to control which links to prefetch, making it a more responsible approach to enhance user experience without the downsides of traditional prefetching methods.
