We often look back at the past in disbelief of how people were able to live differently from the way we do today. Without iPhones, for example. Newcomers fail to realize that our present is fairly new, and that those "ancient" times that include clunky inventions and tailored outfits were not that long ago. Many years from now, our grandchildren and great grandchildren will look back at the way we live today and scratch their heads wondering how we could have survived without the iPhone 20s, or something even newer. So it goes.
