Vibe Coding Confirmed Problematic as Anticipated by Experts

The emergence of “vibe coding,” a term popularized by OpenAI cofounder Andrej Karpathy in February 2025, has sparked considerable debate among experts. Karpathy described vibe coding as a straightforward approach, involving seeing, saying, running, and copying code that mostly functions. However, various concerns have arisen about this coding method, highlighting potential pitfalls.

Concerns Surrounding Vibe Coding

Vibe coding offers immediate gratification and is accessible to anyone. Yet, experts warn of significant drawbacks. Security risks are one concern, along with the diminishing entry-level opportunities for burgeoning coders typically necessary for skill development. Employers still require expert developers, but the pathway to these roles is narrowing.

Impact on Open Source Software

A pivotal study titled “Vibe Coding Kills Open Source” emphasizes the detrimental effects of vibe coding on open-source software (OSS). The authors found that AI tools primarily mine existing OSS repositories without contributing original content. As AI-generated code relies heavily on human-created examples, the sustainability of future projects is at stake. Miklós Koren, one of the authors, stated, “Vibe coding is not sustainable without open source.”

OSS is typically free and editable, allowing users to collaborate and enhance software. This communal effort fosters improvement but is threatened when AI mediates interactions. Vibe coding tends to obscure the contributions of individual developers, weakening the user engagement essential for OSS sustainability.

• AI tools reduce development costs by 10-12%.
• OSS maintainers risk losing up to 70% of their revenue.

While AI coding tools enhance productivity, the overall economic model for OSS maintainers is jeopardized. A shift in the OSS funding structure may be necessary to ensure viability. The authors propose a Spotify-like model that compensates OSS maintainers based on usage, a concept that requires buy-in from AI companies.

Koren underscored the urgency of addressing these issues, stating, “If OSS collapses, vibe coding will go down with it.” The discussion around vibe coding and its implications on software development continues, revealing a complex relationship between AI technology and community-driven initiatives.
