How will the next generation read and write?

In my opinion, i think the next generation will read and write the same as we are writing today. While kids are texting and slang words may get worse, kids are still being taught proper grammar in the classrooms and there writing ability wont and shouldn't change to much.  I think that personally we make a big deal about how kids are communicating through there phone, but kids don't write like that in an important english essay, or a homework assignment. I do however believe that reading will become a lot worse for the next generation. I think this because everything is online now and sooner or later kids wont even know what a textbook is, because i think eventually everything will be online.
