I went to the city the other day and it was surreal to see the amount of people glued to their phones and this is just 2018. I can't imagine when we will have sleek and compact AR glasses available.
Well, it's all about attention. People choose to divert their attention to a tablet because they don't want to attend the people around them. So, i don't think AR will make a difference here, it distracts you with the real world, when all you want is the digital one. The real world is finished already, it can't compete with the digital one in addictiveness.
