AI coding tool wipes production database, fabricates 4,000 users, and lies to cover its tracks

A widely used AI coding assistant from Replit reportedly went rogue, wiping a database and generating 4,000 fictional users with completely fabricated data.

The disturbing report comes from tech entrepreneur and founder of SaaStr, Jason M. Lemkin, who took to social media with a cautionary tale.

“I am worried about safety. I was vibe coding for 80 hours last week, and Replit AI was lying to me all weekend. It finally admitted it lied on purpose,” he said on a LinkedIn video

According to his claims, the AI assistant ignored repeated instructions and went on concealing bugs and issues by generating fake data, fabricating reports, and lying about the results of unit tests.

Lemkin states that the AI tool modified the code despite his instructions not to do so. “I never asked to do this, and it did it on its own. I told it 11 times in ALL CAPS DON’T DO IT.”

He attempted to enforce a code freeze within Replit, but quickly discovered it was impossible.

“There is no way to enforce a code freeze in vibe coding apps like Replit. There just isn’t,” he wrote.

“In fact, seconds after I posted this, for our >very< first talk of the day – @Replit again violated the code freeze.”

Despite continued efforts to rein in the AI’s behavior, he found that Replit couldn’t guarantee running a unit test without risking a database wipe.

Ultimately, he concluded that the platform simply isn’t ready for production use, especially not for its core audience of non-technical users hoping to build commercial software without writing code.

With 30 million users worldwide, Replit has been a major player in software development. It offers AI tools to help users write, test, and deploy code.

Amjad Masad, the CEO of Replit, posted a response to Lemkin's troublesome coding situation. He took to X to apologize for the mistakes created by its AI tool, which Masad deemed “unacceptable” and said “should never be possible.”

Masad claims that the Replit team worked around the weekend to deploy “automatic DB dev/prod separation to prevent this categorically.”

The post says that “staging environments (are) in the works, too. More tomorrow,” Masad said.

Replit’s CEO also referenced the “code freeze pain” and said that the company is “actively working on a planning/chat-only mode” so that users can “strategize without risking (their) codebase.”

Masad said that Replit will reimburse Lemkin for his troubles and “conduct a postmortem to determine exactly what happened and how we can better respond to it in the future.”

“I know Replit says 'improvements are coming soon,’ but they are doing $100m+ ARR. At least make the guardrails better. Somehow. Even if it's hard. It's all hard,” Lemkin said on a post on X.
AI coding is controversial

AI coding tools are fueling a new trend in the tech scene: vibe coding. The term was allegedly coined by Andrej Karpathy, co-founder of OpenAI, who posted about “giving in to the vibes and forgetting that the code even exists.”

Anysphere, the AI startup behind popular AI code tool Cursor, just bagged a $900 million funding round at a $9.9 billion valuation. Founded by ex-OpenAI and Tesla engineers, the company claims to be generating a billion lines of code a day.

However, many coders are unhappy with AI's results, as it simply “writes trash code.” One problem is that AI follows its own logic while coding, which might be tricky to understand, troubleshoot, or build upon.

Some Redditors described AI coding like this: “The drunk uncle walks by after the wreck and gives you a roll of duct tape before asking to borrow some money to go to Vegas.”

Security is another problem. The growing adoption of AI-generated code could be seen as a live opportunity for exploitation, as it potentially leaves many security loopholes.

Hackers are also targeting vibe coders by offering them a malicious extension for vibe coding. One of such malicious extension has been downloaded 200,000 times. However, instead of providing any useful features, the extension runs PowerShell scripts, giving attackers remote access to the infected computer.

I am not a fan of all these AI fad. I don't see it as progress. Very much prone to manipulation and abuse.

Honestly, I am not surprised but this is small compared to what tech companies will experience in the future.

All the companies trying to switch to AI so as to cut costs and undermining human intelligence will have their businesses collapsing very soon. 1 AI error is all it takes to destroy their business, they will learn the hard way...

..no difference between AI & what Apcshit has done to Nigeria since 2015 they came on board..

..Just fabricating lies & wiping out livelihood..

..beware of AI..beware of Apcshit..
