If we put aside everyone who's unable to literally read more than one sentence, I can imagine a different scenario as well.
I have a coworker who's very likely autistic and his type of working is, writing down everything. At first that sounds helpful, you can always go back into the documentation and every ticket has all the information. But for me personally this incredibly annoying. Why? Because he has no filter of compacting information. Some easy tasks, like for instance "CEO wants access to test results of XY", will result in a 20 pages essay.
Again you might think that I'm maybe overreacting, but when you have 20 or 30 tickets that way and are busy solving something that requires more brain power and you got to jump in between issues - because sometimes you're waiting for a reply or other people to act - then it's super frustrating if you jump and it's again a 20 pages essay you got to read. This is super time consuming, frustrating and literally makes me angry.
This might be useful if you have a super complex project and important scientific workflows where you're highly urged to not do mistakes, but otherwise it's way too much. In my eyes this is not efficient working.
My coworker is smart, maybe too smart to work with us, but he also lacks a filter of what information is important and which isn't.
I try my best to not work on any projects with him and skip over most of his writing. Going as far as writing it down myself, to not have to go into his tickets and read his unfiltered "brain puke" and waste time and energy trying to find the gist.
Have you tried to be brief? Maybe throw the text into chatGPT and compare a condensed result with your own?
Also btw, if you're really autistic, then your brain literally works different, compared to how most other people process information and sensory impressions. At least that's what I'd assum autism is about, but maybe I'm wrong.
