How Technology is Changing

I think that it's kind of crazy how everything in the future will be done by computer.Talking about how schools will change and that not everyone is educated for this stuff. In ways I feel like im going to school to become a teacher and feel like your trying to tell me that im waisting my time because in the future technology is the main concern. So everything else I learn is not as important. I realize that in this course im having a hard time than all the others course we had this past year. So does that mean im not going make it the future because im not familiar with technology.
