Do monuments still matter? Does art still matter? Does the human condition still matter? They are all connected.
All these things still and always will, matter. Geo-location on a silly device will not replace the physical world around us – and if it does, well, we are really screwed then.
Larger than life monuments capture the larger than life people and events that helped shaped the country and the world. A human figure carved out of a single piece of marble is am amazing thing to behold and should not (and can not) be replaced by a digital representation of it. The digital representation can be a wonderful tool to allow people to experience it, somewhat, without really being there but it will never replace the exact experience.
If technology ultimately makes us feel less connected with our past then technology will be doing us a disservice. Technology should act as a tool that helps us learn about ourselves.
The question often gets asked, why are we here? To me, that’s a simple answer. We are here to learn about ourselves, on all different levels. On a personal level (learning about ones own self) all the way up to the grandest level, to learn about ourselves in the terms of a species. Our actions throughout history exemplify this over and over again. Our thirst for knowledge about our selves is the reason why religion, art, culture, science and technology were developed in the first place. It is why we have the need to explore and create.
Monuments will always matter, they are forever. Granite and stone last longer than a digital hard drive.
