Midjourney had a training phase where he used many different artworks, images, photos, and pictures to become more intelligent. During this phase, this guy used many paintings to learn what a definite style, technique, or method looks like so it can perform like that. In this case, many artists have actually sued AI-powered art generators like Midjourney because it has used their artworks with no permissions, credits, or copyrights. That’s where things become inappropriate.
