How the vibe coding wave began and rapidly changed the IT industry

Andrej Karpathy gave "vibe coding" its name in February 2025. Ten months later, Spotify's most experienced developers had stopped writing their own code.

Peter Sestoft of the IT University of Copenhagen was already well into working with AI when the term appeared. He says the label simply put words on a concept that people in the field already knew: "Og nu blev der sat ord på et begreb, som vi allerede kendte til," meaning that a term had now been given to something they were already familiar with.

The timeline is the core of the story. A term coined in early 2025 was followed within under a year by one of the best-known tech companies in the Nordics reporting that its senior engineers no longer hand-write code. The piece frames this as a rapid shift in the IT industry, and Sestoft's comment suggests the practice was spreading among practitioners before it had a name.

The material available here is only a short opening excerpt of the article. It covers Karpathy's naming of the term, the Spotify development and Sestoft's reaction, but it does not include further detail on how Spotify's developers work, what tools they use, or what Sestoft thinks the consequences are for the industry.

For a Danish and Nordic audience, the relevance lies in the local voices involved: a Copenhagen academic who was already working with AI, and Spotify, a Swedish company, as an example of how quickly working habits in software development are changing.
