Other than that, I'm with you. The need for summarizing is a symptom of our increasingly poor communication and degrading writing skills. That, and SEO optimization which attempts to hit as many keywords as possible.
We're heading in a direction where people will use LLMs to pad their writing, so it will appear more substantial then it actually is. The receiver will then parse it though another LLM, because the writing has now become to convoluted, or they simply don't have the time for a ten page essay (in which case the none padded draft would have sufficed).
Admittedly I have found a few useful cases for LLMs, mostly related to text parsing and information extraction, which can be seen as summarizing I suppose, but mostly I have a pretty negative view of LLMs. Part of it may be me getting older and not fully understanding how they work, partly it's also their deployment in areas where I believe communication should be human to human.
Whilst I agree there is a societal decline, there has also always been a corporate tendency towards verbosity and opaqueness.
The old rule from the days of memos still seems to apply: ignore first paragraph, get positive / negative gist from second, learn about the impact in the third, ignore remainder.
Anything that can be expressed in a few sentences, should be, and I tend not to read media that doesn't abide by that rule. If I'm reading long-form content it's because I am looking for detail and nuance that would be lost in a summary.
I do think a reliable video summary generator could be useful occasionally. Interestingly Orbit seems to work on YouTube, presumably by parsing YT's auto-generated transcript.
