Technology in 20 years

In 20 years I think technology is going to rule the world even more than it is today. I especially think technology will be seen almost entirely in the classroom. I believe technology will be so dominate that you will hardly see any paper, pencils, or books in the classroom. You will see computers or tablets for every student and all homework will be done electronically. I am not saying this is entirely a good thing. I think technology will take a way from students ability to have free thinking but this is what is going to.
