I often wonder myself about this supposedly amazing ability. Like what kind of documents people have which can be summarized in a useful way? A work email? Absolutely out of the question, since LLM can and will miss important parts or context. Spam(inc. robot alerts and similar)/not-spam classification? Maybe, but usually it is either already obvious if these are corporate alerts with specific headers, or if a person talks to the new customers often it is better to double-check manually anyway to not miss stuff. Long complex texts like science papers or law docs? Those usually have abstract already. Some business heavy docs? Maybe, but what's the point, general ideas are usually clear from the doc name and the content is usually numbers and tables and graphs which can't be summarized. Guides to systems? Also have intros and then actual content can't be really summarized or there is no point. What else? Am I missing something?
In a corporate environment most emails are TLDR. Quite often a big boss will forward a mail to the whole department "please read". It's 5 pages of waffle. Is it useful or not? Either I spend ten minutes reading or ignore it, or ask a person or bot for a summary. For a dyslexic person, to read a large block of text that is unclear if it is pointless or not, is a lot of cognitive load that you cannot afford either.
