Are Emojis the Hieroglyphics of Our Time?

I wonder if future humans will enter old collapsed buildings and see emojis lining the walls. What if they see this line-up and have to interpret it? Ate donuts, fries and a whole cake. I pooped, had to close my eyes because it was kinda gross and call the police because an innocent family could be in jeopardy. 

People are having whole conversations with just emojis.

Are emojis part of the degradation of society? Are we seeing language take a L right in front of us? I know, having been around many younger teenagers that soft skills are most certainly taking a hit. 

Kids are having a hard time interacting on a personal level. They don't know how to ask about the well being of a friend or family member, they don't know how to answer questions in an interview. They don't really know how to function in society. 

Of course, I'm not talking about all kids, but I do believe we are producing a subset of society that is finding it more and more difficult to communicate. 

We may have come full circle if we start carving emojis into walls.
