AI destroying mankind has always been a theme, but it's probably not going to be in the form of a physical war. This picture generation will probably have a very negative impact on mankind. Imagination is one of the driving forces of mankind, and so is our desire to realize the things we desire. When these generators become a common thing, human imagination and intelligence will start inevitably degrading. Nobody will bother painting pictures, making music, making video games or movies, when anyone can just see and hear whatever they want instantly. And people will brobably work all day long just so come home and pay to use these generators. This has the potential to destroy mankind by destryoing the human spirit.
