if you generate graphics, story and stuff with llm and make them more pretty through human labour, you still have llm generated crud. Generated story acted by humans is still same as fully generated one. using generated slop as placeholders might be fine, but it most likely still influences what they actually make so still no.

if you are just starting something and have no idea about anything and no mental image about what is what at all, THEN using generated stuff might be okay as an example so you can get the idea what is going on, as long as you stop using anything generated as soon as you can.

llm and any datacenters involved with it need to go up in flames.
