You both are correct to a certain extent but one thing’s for sure, you can put this a lot politer, we are all civilised humans here.
Sure AI indirectly takes away from artists, and sure people believe that art is a waste of time. These are both true to a certain extent and it isn’t black and white. Although many people (me included) don’t agree with the way some use AI, it doesn’t mean we should attack the people who do. They aren’t being malicious to us in any way directly. He’s not trying to sell anything or cause harm, the developer just wanted to make a game and partake in a game jam and prefers to work on the game design aspect as opposed to programming or art. So what? I don’t agree and I wouldn’t follow long pathway of life the same way as he does, but it doesn’t mean that everyone else’s way is inherently wrong.
