Mobile Media Revolution by 2020?!

I came across this video last summer and found it interesting--and scary at the same time. I usually show it when I give presentations about mobile learning. It really makes you think about the future. As I watched the video again just before this post, several questions came to mind:

1. Where are we headed with Mobile Media/Learning? Is the iPad a beginning or a continuation?
   
2. Why are we so afraid of the unknown when it comes to mobile technology in general and specifically in education?
3. How will we address mobile safety as a society (this has got to be one of the 21st century careers that has yet to be created)?
