Simon Sarris makes the case we should treat audiobooks as seriously as we treat books, because listening is a skill just as important as reading:

If you find audiobooks hard to follow, this is all the more reason to want to practice. After all: How long did it take you to learn to read well? Keeping the thread of an uninterrupted narrative, holding your concentration and attention for it against all the other forces, this is a muscle worth stretching. You might find that over time you get better at it, you absorb much more, and it will make you a better listener elsewhere, too. If you try to listen to them on 1.5x speed you are absolutely going the wrong way.

While reading is very different from writing, both skills are incredibly valuable for learning.

If you read a lot of books, give audiobooks a try. I wish I did sooner.
