The article is a little vague on the AI use in this project, and does not seem to tell the whole story. Here is the disclosure of the usage from the git project page:

"AI coding tools were used in developing and debugging this port. My focus has been on matching the original P.T.: comparing builds with PS4 references, identifying discrepancies, testing gameplay and prioritizing fixes.

The project uses the original game assets from the player's own PS4 copy. Optional upscalers and neural rendering use machine-learning models when enabled."

Still pretty vague.

This isn't a commercial product, so I'm not sure why the AI use matters. It's not replacing a paid dev position.

Because AI consumers far more electricity and water than is useful, relative to the value it provides.

It's an indicator of general laziness and of poor quality.

I would hope it hasn't affected anything, but now I'm forced to wonder if this PT is really the same PT that I remember.

Also, commercial projects are not wholly separated from the culture of hobbyists. They inform each other and reflect each other. If hobbyists largely use AI, then yes, commercial projects will too.

There is more than one reason to avoid AI developed software. We have no idea if they used a local model, or are paying one of the shit companies pushing AI into everything. We don't know the skill level of the dev and if they have the ability to quality check the AI code. We don't know if there are potential security vulnerabilities because of AI code (hopefully less likely in this kind of project). That is all in addition to the greater issues with AI.

I am also just fucking sick of seeing people make headlines for typing in to a chat box and having the stupid fucking robot port a game they didn't even make with barely any effort. Fuck these lazy assholes, I'd genuinely rather the game not be ported at all.
