Training Data Is the Science: Why Deleting It After Deployment Undermines Every AI Model Built on It
Across research institutions and commercial laboratories, the datasets used to train artificial intelligence systems are being discarded, compressed beyond utility, or sealed behind proprietary agreements shortly after the models they produced go live. Without access to training data, independent auditors, clinicians, and rival researchers cannot meaningfully evaluate what an AI system learned, what it missed, or why it fails when it does. The scientific record is accumulating AI-derived finding
