Experienced developers using AI as a tool and properly understanding their code base are not slop.

AI slop is when someone with no software development experience prompts a piece of software into existence without any understanding of how that piece of software actually works. The project's are usually heavily pushed by their creators in the initial couple of weeks of creation but are then quickly abandoned when the creator finally realizes neither they nor their AI can maintain the project. Essentially these kinds of projects flood the internet with low quality abandonware.

A newly created open source project coded using AI would be fine if the creators could prove that they understand how to maintain the project and keep it going beyond the initially promoted code and that kind of proof can only come with time.

The big problem is the sheer volume of low quality projects that get abandoned will cause the projects that actually have potential to become needles in haystacks.
