There is nothing new under the sun...we are the same monkeys that we have always been. Technology / circumstances have changed though, somewhat. Nature + Nurture, with the former unchanged and the latter altered might produce something different? But people thought that the internet would solve all the world's problems, and if you replace "internet" with anything else at all, repeat as nauseum, you get life... so no, it both "changed everything", while also changing nothing.
Strong societies beget weak children, who produce vulnerable societies, which after (as?) they fall apart beget strong children. That is what I see anyway, right or wrong. That is why it is important to ask questions as you are doing. Entropic decay can only be overcome with effort. You can't solve the world's problems, only your own - and those who are willing to listen. As an example, we cannot fix Reddit, only make a new place to be better, but that takes WORK.
