I'm noticing one major early effect of them is making extensive, visually consistent, very impressive slide decks accessible to individual workers who need to actually do real work and wouldn't ordinarily have time to make those.

The result is an explosion of pretty bullshit-heavy documents flying around our org, which management loves but which is definitely, so far, net-harmful to productivity.

This comes out if you start asking questions about the documents. "Which of a couple reasonable senses of [term] do you mean, here?" they'll stumble because that was just something the LLM pulled out of the probability-cluster they'd steered it to and they left in because it seemed right-ish, not because they'd actually thought about it and put it there on purpose. They're basically reading it for the first time right alongside you, LOL. Wonderful. So LLM. Much productivity. Wow.

Anyway, since a lot of what managers and execs do is making those kinds of diagrams and tables and such in slide decks, and their own self-marketing within the company is heavily tied to those, I expect they see this great aid to selfishly productive but company un-productive activity as a sign these things will be at least as big a boon to real work. Probably why they still haven't figured out how wrong that is. I suppose they're gonna need a real kick in the ass before they figure out that being good at squeezing their couple novel elements into a big, pretty, standardized, custom-styled but standards-conforming diagram padded out with statistical-likelihoods doesn't translate to being similarly good at everything.
