This video from Jared Handerson, why we can't focus, nails it. And makes me feel old.

Two takeaways:

• You need to give your attention to books, forging a typographic mind.
• Your phone is screaming for your attention, scattering your ability to focus.

My opinion:

If books give (or remind us) of our typographic minds, great. But will the younger generation, digital-first generation, still derive the same benefits? I guess that it will open the gap between readers and non-readers, but I am wondering what the exact implications will be.
