If you don't trust the AI generated code yourself, then you wont benefit from it. And in fact all it does is take resources from the project that you work on, the one that's generating all the value in the first place.

There are strong parallels to the image generation models that generate images in the style of studio ghibli films. Does that benefit studio ghibli? I'd argue not. And if we're not careful, it will to undermine the business model that produced the artwork in the first place (which the AI is not currently capable of doing).
