what technology has come to these days

I think that it is cool that if your sick at cant go to school, that you can use technology so that you can still learn and interact with others at school. it has only been like a century since technolgy was first used and just about every thing has changed or improved. when went from no tech in the 1910 and under to now 100 year later 2013 that if you dont feel good you could just have a camera go to school for you. Im amazed in how people can invent new things to help others with there life.
