Talked about how our society has pretty much no 'absence' any more - it's impossible to get away from everything, even when one takes a sort of "digital fast." 

One interesting note was how so many people are saying that things like Google and wikipedia making knowledge instantly available to anyone will mean the end of any real knowledge is something that has happened many times before.

When the printing press was invented, people thought that making information previously relegated to libraries / institutions available to the public would dilute the knowledge, and that no one would have to remember anything any more.

But even before that, the invention of written language / writing itself caused the exact same concerns - if people could just write things down, there'd be no reason to develop good memory, previously the only way information was passed down.

So in other words, perhaps not all hope is lost. (I wonder who first said that... let me go Google that...)
