Nothing new under the sun.
I must say, I have been trying to read the Bible for the first time end to end (Just finished the Old Testament recently) and if there is one that that stood out apart from the religious aspect, is that human behavior is not radically different today than it was after Adam and Eve were banished.
The technology is different, but the same vices, flaws, lust for power, lies, and antisocial behavior has not changed at all. While the way these things are manifested have indeed changed, the underlying flaws in us as humans have not.
As you said, nothing is new under the sun.
