深度洞見 · 艾聆呈獻 In-depth Insights, Presented by AI Ling Advisory Episode Summary This episode provides an in-depth analysis of one of the 21st century's most unsettling digital concepts: the Dead Internet Theory (DIT). What began as a fringe conspiracy has rapidly evolved into a mainstream diagnosis of our online lives, validated by tech leaders and accelerated by the rise of generative AI. We explore the "felt truth" that the internet is no longer a vibrant space for human interaction, but a hollow facade of bot traffic, algorithmically generated "slop," and sophisticated manipulation. This discussion dissects the theory's two distinct components: the observable phenomenon of a sterile, repetitive online world, and the conspiratorial thesis that this is a deliberate, AI-powered gaslighting operation by powerful entities. We trace the theory's journey from niche forums to mainstream consciousness, examining the key evidence that gives it power—from cybersecurity reports on bot traffic to potent cultural symbols like "Shrimp Jesus" and the "YouTube Inversion." Finally, we analyze the profound psychological and cultural fallout of this "Potemkin internet" and explore the root causes in the internet's original architecture and the perverse incentives of the attention economy.
