That sounds pretty similar to what I get from LLMs regardless of what they're writing for. Any time I get more than a paragraph out from an LLM, it tends to have of a lot of irrelevant details or unnecessary hedging, and I have to either wade through it to find the actual answer or try to convince it to make it more direct.

As someone on the spectrum, this does happen to me with people sometimes too; I struggle when asking a question and getting an answer that doesn't fit the "shape" of what I expect (e.g. asking a yes or no question and getting a relatively long sentence in response that doesn't contain either "yes" or "no" in it, which means I need to do the equivalent of applying it as a diff to my mental model and seeing if there are conflicts). This happens less frequently with other humans though, and on average the amount of effort I need try to figure out what they're saying is a lot lower. This doesn't make it less frustrating when I get that kind of output from an LLM, but it doesn't surprise me all that much that it happens.

I'm sure I do this all the time to people too, though. One of the biggest lessons I've learned in the past several years is that I communicate in ways that I'd probably have trouble understanding in reverse a lot more frequently than I realized, even I still do the things I find confusing from others less often than most people I interact with. I'm sure a lot of people might find this comment to be pretty much exactly like what I'm complaining about even though I feel fairly confident at least in this moment that my point is clear.
