In The ‘Future Book’ Is Here, but It’s Not What We Expected, Craig Mod writes that after years of believing books will fundamentally change in the digital age, it’s simply not happening:

I think we can agree that, in an age of infinite distraction, one of the strongest assets of a “book” as a book is its singular, sustained, distraction-free, blissfully immutable voice.

What has changed, instead, is how books are created:

Instead, technology changed everything that enables a book, fomenting a quiet revolution. Funding, printing, fulfillment, community-building—everything leading up to and supporting a book has shifted meaningfully, even if the containers haven’t. Perhaps the form and interactivity of what we consider a “standard book” will change in the future, as screens become as cheap and durable as paper. But the books made today, held in our hands, digital or print, are Future Books, unfuturistic and inert may they seem.

Or, more succinctly:

Our Future Book is composed of email, tweets, YouTube videos, mailing lists, crowdfunding campaigns, PDF to .mobi converters, Amazon warehouses, and a surge of hyper-affordable offset printers in places like Hong Kong.
