It's just his wet dream. How many things have once been online and aren't any more? How many electronic formats do we have that we can no longer read?
I will always, always, want my own copies of the important stuff, stored on at least two hard drives right here. I don't need CDs or DVDs, no, but I'm damn well keeping DRM-free stuff and the means to play it. And I may be the last generation that wants this stuff. But maybe not.
