How advance will technology be in 50 year?

Technology is the most popular thing trending these days. It is used in every aspect of life. There is not a single person, I would think, that does not use technology is some shape, form or fashion. With that being said, fifty years from now technology will probably run the world. The schools will have some type of portable device to do everything on. For classrooms, technology will replace boards, books and paper and pencils. I also believe technology will put alot of people out of work. For example, the grocery stores could run completely off u-scan: colleges could use more online classes and less classroom: airports upgrading to only self check-in: the internet replacing all the books in the library etc. When it comes to social life, everyone will be walking around with a miniature computer in their pockets. It'll soon be where a person can sit at home and visit there friend in another country and not have to leave their post. Therefore, it will be wise if everyone become familiar with technology.
