Vibe coding (using LLMs to create computer code) was all the rage when 2025 began. By June, the bloom had fallen off the rose. Companies offering platforms and tools for the practice saw dramatic downturns in users. What happened? Evidence points to the traditional market practice of targeting early tech adopters.

Vibe coding was largely sold as a mean of improving efficiency professional coders and, as is their wont, professionals loved it for eliminating what they considered grunt work. But as the fad gained traction in the coding community, there was little evidence that it made coding any better, Rather, it made it possibly worse.

Illusions of efficiency

New studies showed any improvements in coding efficiency were illusions. While the coders assumed the tools made them as much as 50% more efficient, the reality is it made them, on average 19% slower. There were multiple reasons for the drag on efficiency. For one, professional coders know something about the issues of security, compliance, and quality control. LLCs don’t and neither do people without coding experience.
