"Books work, but they're not the complete solution" is a much better title, but then us as the audience don't need to read a multi-page Medium article type rant to know that.

To be honest, you could replace 'book' with 'video', 'article', 'podcast' or any other medium people learn from and the article could stand pretty much as is and give the same general point.

The whole article could probably be more effectively re-written with the focus on time and learning, using different media as well as books as an example and make the point stronger. By choosing books as a focus, the author loses the main point and doesn't really get to it until the end, making the article, as you and other commenters pointed out, ranty and a slog to read through.

I think part of the problem is that the author of TFA sorta "buried the lede" and didn't really get to the point until very near the end. I suspect a lot of people got bored and quit reading before that point. Honestly, I did, and it wasn't until my second reading that I got what he was saying near the end, which is admittedly a somewhat different take.
