Even assuming equal levels of knowledge about the subject, who probably has had the most ideas—you in five minutes of reading or me in five days of stumbling around? All I’m really saying is that we readers sometimes forget how long literary composition can take and how very much lateral thinking can go on in that amount of time.
I think everyone can answer the one who’s stumbled around for 5 days. Writing does take a lot of thought and it’s interesting to think books that took years to make can be read in mere days.
