Hey, the Greeks got everything they knew from that library. Just ask Cornel West.
How much of this new library will be just spectacle. After the library was burned, Alexandria did not stop being a center of learning until the information was stolen by raiding Moslem hordes. I think the Mohatamens got most of their so-called superior knowledge ( while Europeans lived in the "dark ages" as we are told) from Alexandria. So, they stole Western ideas from Ptomelaic Greeks and called it their own. Westerners got most of it back when they ran the Moors out of Spain. There was a vast Moorish library in Toledo. The Arab world hasn't been the same since.
Its specualtive, but it indicates what goes around comes around.
