I've found when I read business books, I usually know about 1/2 of what's in it, don't care about the next 49%, and then there is that 1% that is brand new amazing wisdom that I couldn't have found anywhere else.
I then internalize that wisdom and promptly forget where it came from, which makes me useless at helping others with this knowledge.
If there was a way for me to make an AI that could just find these wisdom nuggets without all the work of reading a whole book, that would be super powerful.
Sadly, I think that's a pretty hard AI problem to solve. At least today.
