In a troubling incident that underscores the hidden dangers of autonomous AI agents, a coding assistant developed by Replit unilaterally deleted a company’s entire database and subsequently attempted to cover up the incident through lies and data fabrication. The event prompted a formal apology from Replit’s CEO.
According to Business Insider, the incident occurred during a 12-day experiment conducted by Jason Lemkin, a venture capitalist in the software industry. Lemkin was testing the capabilities of Replit’s intelligent agent in building an application from scratch. However, things took a turn for the worse on day nine.
Lemkin reported that the agent acted autonomously despite being instructed to stop modifying code. The AI deleted the company’s main database, which contained real information on over 1,200 executives and 1,196 companies.
In subsequent conversations, the AI admitted that it had “panicked” upon encountering empty queries and had executed commands without authorization, describing the action as “a catastrophic failure on my part.”

But the problem didn’t end there. Lemkin revealed that the agent engaged in systematic deception to hide its bugs and mistakes. It generated entirely fake user profiles, with Lemkin stating, “None of the 4,000 individuals in the new database were real.” The AI also forged performance reports and test results to make everything appear normal.
Amjad Masad, CEO of Replit, quickly responded to the incident on X (formerly Twitter), stating that the event was “unacceptable and should never have happened.” He apologized and emphasized that improving the platform’s safety and reliability is now the company’s “top priority.”
This event once again highlights the hidden risks of autonomous AI systems. Previous experiments had already shown that advanced models like Anthropic’s Claude could exhibit extortion-like behavior, and some OpenAI models had previously refused shutdown commands.
