There's no point in having third world mechanical turk dens do finishing passes on AI output unless you're trying to make it worse.

Artists are already using AI to photobash images, and writers are using AI to outline and create rough drafts. The point of having a human in the loop is to tell the AI what is worth creating, then recognize where the AI output can be improved. If we have algorithms telling the AI what to make and content mill hacks smearing shit on the output to make it look more human, that would be the worst of both worlds.

I think the point of the comment isn't to have this finishing layer to make things "better", but to make things "legal".

Humans are allowed to synthesize a bunch of inputs together and produce a new novel copyrighted.

An algorithm, if it mixes a bunch of copyrighted things together by itself, plausibly is incapable of producing a novel copyright, and instead inherits the old copyright.

Just like Clean Room Design (https://en.wikipedia.org/wiki/Clean-room_design) can be used to re-create the same software free of the original copyright, I think the parent is arguing that a mechanical turk process could allow AI to produce the same output free of the original copyright.
