Most of the focus on this isn't the code. It's the art and music that make up the experience.

This is discussed right in the article.

> For Kanaris-Sotiriou, the question of adopting the use of gen AI to make games was an easy one to answer. “The foundations that it’s built upon, the idea of using other people’s work without permission to generate artwork [...] are unfair,” he says.

I personally think using AI assistance for the code is much less intrusive than using AI for the art and music -- the code isn't as directly experienced by the player as the art.

Much of it comes from people feeling challenged and threatened by the new tech so they construct elaborate philosophies to justify how they feel, but this rapidly crumbles when you look closer. For instance, artists felt threatened by generative AI and came up with a narrative about copyright stuff. But then Adobe comes along with generative AI which doesn't have the copyright issue and how do those same artists respond? With a loud "fuck you" to Adobe, because the root of their objection was never copyright but rather what the new technology would do to their established careers.

In this atmosphere, I think it's easy to perceive an implied rejection of and threat to AI generated code, even if the focus is on art assets, because people aren't being entirely direct and forthright about exactly what it is they're upset about, and that makes for a landmine field.
