T-Rex: Ah, the great Library of Alexandria! A repository of learning founded in the 3rd century BC, this library has become a powerful symbol for knowledge.

T-Rex: Especially since it was destroyed by fire or maybe looting a few centuries later!

T-Rex: Oh, what knowledge we have lost! What revelations were written on those ancient papyrus scrolls, now entirely beyond our grasp? With this lost information, could the industrial revolution have arrived a thousand years earlier? The only answer I can offer is an enthusiastic "perhaps!" followed by a wide-eyed "who knows??"

Utahraptor: Whoah, I think you're putting too much into this, T-Rex!
T-Rex: It was a pretty great library!

Utahraptor: Yeah, but you're treating the actual libraries (plural) as a symbol, which only confuses what actually happened historically. Certainly SOME ancient knowledge was lost, but I think it's disingenuous to suggest that its loss meant our development was set back thousands of years!

T-Rex: You're saying that by building up the legend, I do a disservice to the actual libraries? Well, I've got news for you, my friend!
T-Rex: Um!
T-Rex: The news is, you make some convincing arguments!
