It's asinine that you think the sell it back to us argument falls short.
Not only does it distill our history to try to sound like some average version of us, it sounds like the blandest versions of us... And then sells this back to us.
From a coding standpoint, the tech is good and gets the job done. The pillaging of all other aspects of human history is just sad. With the only solace I'm seeing is that future training has to train on the dogshit versions of the internet that are now infected with LLM content.
