Earlier quoted context omitted.
I can only speak for myself, but a Metaverse consisting of infinite procedural slop sounds about as appealing as reading infinite LLM generated books, that is, not at all. "Cost to zero" implies drinking directly from the AI firehose with no human in the loop (those cost money) and entertainment produced in that manner is still dire, even in the relatively mature field of pure text generation.
I can only speak for myself, but a large and growing proportion of the text I read every day is LLM output. If Claude and Deepseek produce slop, then it's a far higher calibre of slop than most human writers could aspire to.
I've noticed obvious LLM output on low quality news sites, but I don't tend to read them anyway. Maybe all the comments I read are from LLMs and I just don't realise?
