What will have changed by the year 2020n in our schools.  One that I think will change is probably no more teachers.  we would probably have robots managing our classrooms.  Another would be that everything will on computer no textbooks.  Probably the state test will not be at existence, in which I hope that it will not be around.  We will be using those Ipads to be doing our work and then turn in assignments.  As for food will it would be kind of hard to have a robot cook the food, so I think that the ladies will probably still be there and just that they will have a quicker way to do things.
