LLM Summary:Comprehensive synthesis showing human deepfake detection has fallen to 24.5% for video and 55% overall (barely above chance), with AI detectors dropping from 90%+ to 60% on novel fakes. Economic impact quantified at $78-89B annually; authentication collapse timeline estimated 2025-2028 with technical solutions (C2PA provenance, hardware attestation) showing limited adoption despite 6,000+ members.
Critical Insights (4):
ClaimAuthentication collapse could occur by 2028, creating a 'liar's dividend' where real evidence is dismissed as potentially fake, fundamentally undermining digital evidence in journalism, law enforcement, and science.S:3.5I:5.0A:4.0
Counterint.Detection systems face fundamental asymmetric disadvantages where generators only need one success while detectors must catch all fakes, and generators can train against detectors while detectors cannot train on future generators.S:4.5I:4.0A:4.0
Quant.Current AI content detection has already failed catastrophically, with text detection at ~50% accuracy (near random chance) and major platforms like OpenAI discontinuing their AI classifiers due to unreliability.S:4.0I:4.5A:3.5

By 2028, no reliable way exists to distinguish AI-generated content from human-created content. Today’s trajectory points there: human detection accuracy has already fallen to 24.5% for deepfake video and 55% overall—barely better than random guessing. Detection tools that achieve 90%+ accuracy on training data drop to 60% on novel fakes. Watermarks can be stripped. Provenance systems have 6,000+ members but remain far from universal adoption.
This isn’t about any single piece of content—it’s about the collapse of authentication as a concept. When anything can be faked, everything becomes deniable. The economic cost of this epistemic uncertainty already reaches $78-89 billion annually in market losses, reputational damage, and public health misinformation.
Key finding: A meta-analysis of 56 papers found overall human deepfake detection accuracy was 55.54% (95% CI [48.87, 62.10])—not significantly better than chance. Only 0.1% of participants in an iProov study correctly identified all fake and real media.
