Reading a book, say 10 hours, is like a meditation on an idea: you get numerous examples of it and a variety ways of thinking about it.

Our brains learn best when they encounter something often across time (spaced repetition).

Reading a single tweet may summarize the book, but the chances of you recalling the idea in an appropriate situation is much lower than if you had spent hours on it.

I agree, and there are many books which are well worth the time it takes to read them. All I'm saying is that there are many other books which aren't.

I'd go further:

"Use checklists." - @AtulGawande

There, now you don't need to read the book.
