There are literally image generation tools that are open-source. Even Krita has a plugin available. There are multiple datasets that can be trained on, other than the one that flagrantly infringed everyone’s copyrights, and there is no shortage of instructions online for how people can put together their own datasets for training. All of this can be run offline.

So no, anyone has everything they need to do this right, right now if they want to. Getting hysterical about it, and dishonestly claiming that it all “steals” from artists helps no one.
