This chap thinks so. And he has some interesting points.
demise of books
Mostly his argument hinges on the developing world.
So you advance literacy in Africa and Asia. You need books. You need a lot of books. A lot of trees…
When phones came to Asia, they didn’t start with miles of copper wire. They used cell towers…
When electrical power comes to remove villages, it doesn’t come so much with power lines, but solar panels.

Personally, I think the market IS shifting faster than anybody had predicted. I don’t think it’ll go quite that fast, because book lovers are sentimental about books—BUT—if you’re sitting in a village in Africa, a laptop with 10,000 books installed is a library. And the classics, textbooks, and reference books will probably be the mass of books that does go that direction. The outlay school districts make in books is huge.

So what happens when that money goes, not to, say, venerable old Putnam or MacMillan, but to Microsoft, and the makers of e-readers? Personally, my money is on the Very Cheap Laptop for that job, because it doubles as a math-science-internet machine. And the cost is about equal.

But what happens to Putnam and MacMillan?

What happens when Johnny’s dog eats not just his homework, but his entire laptop? I’m sorry, Miss Jones, my computer crashed?

Not, Report to the principal’s office, but Report to IT.

It’s an interesting new world out there. Again, my bet is a long, long period when we’ll see Original print books, and then people hawking copies of Original Print, etc.

Heaven help us if we have a major Coronal Mass Ejection equalling the one in the 1800’s and a few months (or years) off the grid.

Of course by week 1, half the country would be gibbering lunatics.
