Minecraft creator Markus Persson posted that he must admit he is enjoying vibe coding, perhaps he was a little wrong before.

This admission is a far cry from his stance earlier this year. In January, he wrote that using AI to write code is still a terrible idea, and that advocates are either incompetent or evil, stating that programming is about logic, not typing, and likened it to letting models write laws. In mid-July, he tweeted "Reject AI," which garnered millions of views. About a week later, he softened his stance: unable to find satisfactory programmers, he prepared to use vibe coding for tools like map editors and node graphs, saying he wouldn't feel too guilty about firing chatbots.

In the following days, he began using Claude to find use cases, joking about whether he could still mock this type of person after becoming a vibe coder himself, and mentioned that his earlier opposition was actually a suppressed, useful thought for a long time. In August, he suggested he might need to admit he was wrong and shared conversation records; he also assured that he would maintain the foundation of his works. He noted that models could create WGSL syntax highlighting plugins all at once, which are indeed useful scaffolding he was too lazy to write. A post on September 22 shifted his tone from tentative to enjoying it. Some responses included laughter, including from Elon Musk.

Persson is currently working on a dungeon crawler project called Levers and Chests. He has limited AI to internal tools rather than claiming core gameplay is handed over to models. The difficulty in hiring is the publicly stated reason for this shift: the tool layer can be outsourced to generators, while he still wants to retain control over the foundational logic.

In market mechanisms, this is a cultural licensing event. The buyers are model and editor companies that want to legitimize coding agents; the sellers are independent developers who regard "handwriting every line" as part of their identity. Funding does not move due to a single admission of error, but a shift in opinion leaders will reduce internal resistance to introducing agents in studios. Beneficiaries include coding products like Claude, while those still branding themselves by rejecting AI face pressure.

On a supplementary note, vibe coding refers to describing requirements in natural language, having models write, and often running code directly. Persson has not disclosed the paid tier of the model he is using, the proportion of generated code in his repository, or whether core gameplay has been handed over to agents.
