A climate of tension arose among players after a video shared on X (formerly Twitter) displayed a technological feat considered almost impossible. The video showed the character Steve from Minecraft fighting bosses in medieval settings from the game Elden Ring, using his square sword.
More than just a character swap, the recording presented the Minecraft interface and gameplay perfectly integrated into the mechanics and environments of Elden Ring. This demonstration caused great surprise and confusion among viewers.
Although game modification, known as 'mods,' has existed since the beginning of video games and can be a starting point for those who wish to learn programming, the integration of the two software, which are fundamentally different in their codes, represents an extraordinary technical level. In the past, such a fusion would require immense effort even from the most experienced programmers, but today this is accessible to many amateurs thanks to artificial intelligence.
During this period, the internet was flooded with other similar combinations, such as Super Mario in Elden Ring, Skate in Call of Duty, and Spider-Man in the Batman game. It is believed that most of these mods were developed with the assistance of large language models, such as Claude and Chat GPT, which have taken over much of the current programming.
This practice received the name 'vibe coding.' The term was created by researcher Andrej Karpathy in 2025 and describes programming done by amateurs with AI support, often carelessly, following only the 'vibe' (hence the name).
Recently, 'vibe coding' was added to the online version of Merriam-Webster, the most traditional English dictionary in the United States, whose origins date back to 1806. Other terms that entered the list this last year include 'Agentic,' 'Natural language processing,' and 'Prompt engineering.'
According to Merriam-Webster, 'vibe coding' refers to the practice of coding, creating web pages, or developing applications simply by instructing an AI program what is desired, allowing it to generate the product. In this modality, the programmer does not need to understand the functioning or the reason for the code and often has to accept the presence of certain errors and flaws.
This is the most controversial point of 'vibe coding.' Although AIs have been trained on trillions of lines of code and can read, interpret, and write complete and functional code from a single command, they still make many mistakes and do not always build programs in the most efficient way.
Besides short videos on social media, the game mixes shown last week rarely work for long without showing some defect. Few of these programs have been released to the public, with the mod combining Minecraft with Skyrim being a rare exception, whose result, according to those who played, is still full of flaws.
Although this may be an inconvenience in the context of video games, 'vibe coding' is already used by various companies in creating software that often contains personal data. In systems that handle sensitive or confidential information, a lapse in the code can generate a serious vulnerability. A study conducted last year revealed that 45% of code generated by artificial intelligence fails security tests, and this percentage rises to 72% when it comes specifically to Java code.
