Jason Schreier released the full transcript of the interview and Swen Vincke never said they had “placeholder concept art” actually, he said that the artists had used AI to generate images that they then used as reference while drawing concept art. In the full interview he doesn’t even seem particularly impressed with AI, says that it doesn’t improve productivity much and implies that it is disappointing. I honestly respect Larian for actually coming out and sharing their experiences with using AI, even if I agree they should probably stop using it entirely, rather than doing what most other studios do and simply hide it under a rug and refuse to talk about it.
