I mean, what do you think PSSR is?
In the article is says it's not aiming to replace human models (so no generative AI for models) but to improve tools and get results faster, and that is where AI should be used.
The thing is, how intrusive are they willing to get, and how much devs would be forced to adapt to it? That can indeed be concerning.
He mentioned Horizon Zero Dawn Remastered as an example and I've never read anything bad about AI from any players or devs, so at least until now, I don't see a problem, actually the PSSR update has been exceptionally praised, as is the Sophy AI on GT7.
AI is not always a problem, how intrusive it can get is.
