When a professor trusted ChatGPT to help manage his research, he didn’t expect the tool to erase two full years of work with a single click. But that’s exactly what happened — and the worst part is that OpenAI couldn’t restore any of it. This incident is a stark reminder that AI convenience comes with real‑world risks.
It’s evident that most, if not everyone, has transitioned into the digital era. Gone are the days when we used to depend on physical files and flash drives as some of the conventional ways of saving important data and information.
At that moment, all of my chats were permanently deleted and the project folders were emptied — two years of carefully structured academic work disappeared. No warning appeared. There was no undo option. Just a blank page. Fortunately, I had saved partial copies of some conversations and materials, but large parts of my work were lost forever.

The professor indicated that he initially that that it was a mistake, prompting him to confirm if he had indeed lost his data across multiple browsers, devices, and networks. His efforts to clear the cache, reinstall the app, and even change the settings back and forth were rendered futile.
He attempted to contact OpenAI for some support, but the first response came from an AI agent. He was able to get through to a human employee after making several attempts. Unfortunately, he wasn’t able to restore his data.
While speaking to Nature, OpenAI indicated that:
“Regarding additional warnings and recovery, we do provide a confirmation prompt before a user permanently deletes a chat. However, once deleted, content cannot be recovered via the user interface, application programming interfaces (APIs), or support, as this aligns with privacy best practices and legal requirements around user data.
For data protection, we always recommend users maintain personal backups for professional work.”
To that end, the professor highlighted the importance of having elaborate measures in place to avoid such occurrences through warnings about irreversible deletion, a recovery option, and more:
“If a single click can irrevocably delete years of work, ChatGPT cannot, in my opinion and on the basis of my experience, be considered completely safe for professional use. As a paying subscriber (€20 per month, or US$23), I assumed basic protective measures would be in place, including a warning about irreversible deletion, a recovery option, albeit time-limited, and backups or redundancy.”
This incident underscores the importance of always having a backup for your backup. Beyond storing data in the cloud, it’s wise to take it a step further by keeping a physical backup as well.
Losing two years of work in seconds is the kind of nightmare that sticks with you. As AI becomes more embedded in our workflows, incidents like this will force companies to rethink how they protect user data — or risk losing trust entirely.
