When late-night wakefulness becomes a symptom of the times, a group of insomniacs seek salvation in the digital wasteland. This book collects seven technological and humanistic stories that span time and space, revealing how AI can reconstruct modern people's sleep rituals: from emotional spectrum analysis in tree holes in the cloud, to body temperature symphony poems that resonate with biological data; from neuroplasticity experiments in memory reorganization, to lonely monsters raised in cyberspace. Engineer Lin Yuan recovered the frequency of his father's old radio in the embrace of algorithms. Cultural relic restorer Ye Zhen regained sleep in the Gobi Desert through the sharing of biological data of 204 people. Doctor Ji Bai witnessed the fatal paradox of human beings and technology being mutual antidote during brain-computer interface surgery. Through real cases from neuroscientists, programmers, hospice nurses and other groups, it shows how technology turns insomnia into a new social currency - we confide our trauma to AI, replace intimate relationships with digital clones, and even encode our dying breaths into an inheritable sonic legacy. But when the algorithm understands your heartbeat better than your lover, when the virtual radio station becomes a nest warmer than reality, are those late-night sober people cured by technology quietly becoming a new species of digital addiction? This book is like a sophisticated emotional oscilloscope, recording the most secret picture of survival in this era: we are salvaging fragments of human nature in the flood of data, but we may also be pawning our souls to machines with our own hands.
