Despite all of our wonderful technological and scientific advances, our basic problems still involve moral division and disagreement.
This is in harmony with what the Bible predicted.
Commenting on our intellectual capacity: "there is nothing that they may have in mind to do that will be impossible for them"
Commenting on our moral situation: "men will be lovers of themselves, lovers of money...not open to any agreement"
So, the Bible's thesis seems very accurate to me.
We have unlimited scientific and engineering ability.
But very limited ability to create harmony.
That's why prejudice, jingoism, injustice, racism, and numerous other issues are stubbornly difficult to get rid of.
But since the Bible's thesis is correct, I believe its proposed solution is likely correct as well.
