The insights and characterisations of human behaviour found in ancient records sometime shock me with their accuracy and depth. Human nature has not changed and it was well, if not better understood, Millenia ago.
The plague killed way more people than nukes ever did, and there was no way to stop it until people understood what spread it. Of course technology has bright sides as well. Without medicine and many other discoveries we would not be where we are today.
I think if anything, the talk about moral decline can be ignored completely. It seems people have been complaining about moral decline since earliest written records.
