I'm a huge believer in doing plenty of research about what to read. The simple rationale: it takes a tiny amount of time to learn about a book relative to the time it takes to read it. Even when I get a sense a book is bad, I still tend to spend at least a couple of hours before making the tough call not to bother reading further (I handled one literally 5 minutes ago that wasted a good few hours of my life). I'm not saying AI summaries solve this problem entirely, but they're just one additional avenue for consultation that might only take a minute or two and potentially save hours. It might improve my hit rate from - I dunno - 70% to 80%. Same idea for videos/articles/other media.
In graduate school for example, it was pretty painfully obvious that most people didn't actually read a book and come to their own conclusions, but rather read summaries from people they already agreed with and worked backwards from there, especially on more theoretical matters.
I feel like on the long term this just leads to a person superficially knowing a lot about a wide variety of topics, but never truly going deep and gaining real understanding on any of them- it's less "knowing" and more the feeling of knowing.
Again, not saying this in an accusatory way because I totally do engage in this behavior too, I think everyone does to some degree, but I just feel the older I get, the less valuable this sort of information is. It's great for broad context and certain situations I suppose, but in a lot of areas I consider myself an expert, I would probably strongly disagree with summaries given on subjects and they also tend to miss finer details or qualifying points that are addressed with proper context.
There are FAR too many dimensions like word choice, sentence style, allusion, etc, that resist effective summarization.
Is it that hard to determine that a book is worth reading where worth is measured from your perspective? It's usually pretty easy, at least for technical books. Fiction books are another story, but that's life. Having some unknown stochastic system giving me a decision based upon some unknown statistical data is not something I'm particularly interested in. I'm interested in my stochastic system and decision making. Trying to automate life away is a fool's errand.
