That's not true at all, human tends to come through (in a way I didn't notice pre-LLM) with varied tone, with opinions injected, and with varying degrees of weight to different components, in all but the most egregious of examples (linkedin motivation pieces, apple marketing speak).

LLMs have a bunch of tricks for dressing up their infodumps, but they are almost purely infodumps, and no real opinion comes through. There's no sense of more importance to one statement or the other, it's all monotone (and usually over the top.)
