Where non-fiction books have a bad signal-to-noise ratio but still provide interesting insights begetting a summary, the best service can be done by a new motivated writer: trying to merely summarize a book squashes the "space" in which insight can deeply take place, as opposed to digesting the message and crafting a new message, an amalgam of ideas from another and another almost harmless business book, into something new, more dense and hopefully superseding. It's a natural evolution of the world's knowledge and books perfectly encapsulate the writer and reader's span and frame of mind leading to good analytical learning.
