Which position of IT and ubiquitous technology will it be after 20 years?

20년 후, IT 그리고 유비쿼터스 어디까지 갈까?

I forecasted how much IT and ubiquitous technology will grow after 20 years. First of all, 1 think the goal of ubiquitous technology and relative main technology is our life. 1 will give examples of ubiquitous technology that affects travel, school and family life and how much it has changed. Lastly I will check the problems and securities in ubiquitous technology. By that time, we will have meaningful time to inspect the change of future technology.
