That's true. I would assume that we would be able to regain most of the basic "this is what makes us the 21st century" information. Almost everything else, in my mind, would be of questionable value to the new society. If Facebook went dark, if Google went dark, Yahoo, Microsoft, hell even Wikipedia; yeah there'd be significant loss and it would take a long time to recover from. But the benefit of the information age versus the destruction of the Library of Alexandria is that you can't just destroy the Library and all that knowledge is gone. There's a wealth of information and culture on my computer alone. If the biggest sources of knowledge were gone tomorrow, individuals would be able to rebuild the basics of the information age very quickly. We might be set back to 1970, but without the literal decimation of the human population, there's no way we'd be set back to the stone age.
