As seen in this academic paper, AR is simplifying our lives and jobs, making them more productive with less effort, and bringing us closer together as humans. This can be be augmenting users, physical objects, or the environment which surrounds them.
Paper, as show in the Ariel and EVA examples and the example seen in class where we can se the human body, is a material which is easy for AR to be used upon. I believe it is the combination between something physical which has been used for ages and new technological tools. It stops serving as a sheet where you write once and dispose it, and it has become more user friendly than digitized "paper".
A key characteristic about AR is it facilitates everyday life. In the following video we see Elon Musk showing and speaking about the future of industrial design and how it is employed at Space X.
