There would many reasons one shouldnt give up on a better learning system.
1. I happened to measure the time it takes to read a book word for word, and my observations are horrible. It takes way too much time to push eyes across the page than to comprehend what the information is about.
2. In regular reading, you read in the manner the author wants you to read. You may not always find this a better fashion.
3. Most of the times you spend a lot of time reading something only to find you wasted all of the time and gained particularly nothing.
