As we advance as a civilization, we always leave behind relics with history and culture attached to them which brings about a form of sentiment for us. But a lot of these relics take up space that could instead be used efficiently to help our species. You have relics that can come in the form of murals, modern art or even buildings, some of which could be religious, like statues, temples or even churches. But they're outdated, we don't need them anymore, we keep them around for the sentiment and not because they provide any practical use to our civilization.
We could do so much more if we simply documented these things and replaced them with something far better for our future generations. Schools, hospitals, science labs of all kinds of fields. It would drive more knowledge into towns or cities, more opportunity for children to grow up safe and have a vast knowledge about their universe when they reach adulthood.
If anything, Augmented Reality technology might actually allow us to revisit ancient monuments of the world without having to go there. Maybe even those that no longer exist. And we'll be able to have that experience exactly as if it were happening in real life, right in front of you. History isn't going anywhere when those relics are taken down, it's simply going to be remembered a different way from how people remembered back then.
I'd love for you guys to join in here and read what you have to say on this topic.
