Automate creation of the content which must be created but is useless and ignored by everyone. Like advertisements, both short and long. And then automate receiving and deleting such useless content. It's like a self-propagating smam+antispam machine. Same with pictures and maybe videos soon. Some pictures much be placed in some spots, like headers (aka ads) of the articles, and are now massively replaced with generated content. After we will be swamped with these pics, people will start working on filtering them with the neural nets. Very useful tech as we can see :)

> So let's freeze frame right here. What is this thing actually good for? Give me even one killer app worth one hundred billion dollars.

Propaganda bots to flood social media.

And most other forms of advertising. Anything where objective truth doesn't matter and quantity is more important than absolute quality is a great fit for LLMs.
