I think "can we", rather than "will we", is the question for current research. "Will we go back" is really asking whether or not we will find ourselves in social situations where we aren't using cameras and recorded imagery to supplement or stand in place of our perception and memory - certainly all of us will find ourselves in low-tech situations, some more often than others.
"Can we go back" is the question of how the technology is altering our capacities, so that when we *do* find ourselves in low-tech situations, we are effectively maladapted. So, to my mind (having studied visual adaptation in several contexts), the research question is really about adaptation - how do memory functions adapt to lower demand availed by technology, and how does this adaptation interact with low-tech situations?
