Marcel Bucher, a plant-sciences professor at the University of Cologne, reports in Nature that in August he disabled ChatGPT’s 'data consent' setting and permanently lost two years of chats and project folders. He says reinstalling, contacting OpenAI support and human agents failed to recover files. The episode—and the social-media mockery it generated—raises concerns about vendor accountability, institutional AI pressure, and data governance.
Key Points
- 1Loses two years of ChatGPT chats after disabling data-consent setting, with no recovery option.
- 2Highlights lack of archival safeguards and accountability in generative-AI tools used for professional work.
- 3Urges practitioners and institutions to require backups, policies, and vendor transparency before integrating AI.
Scoring Rationale
Credible Nature first-hand report highlights systemic AI data-governance risks, but single-case anecdote limits broader technical conclusions.
