This is not the future. This is now. At the school district where I volunteer as a computer instructor, all the first graders already have a Google account that will follow them throughout their grades. In fact their user names include the year they are expected to graduate. They are teaching first graders how to use Google docs. Editing a Google doc is their first big lesson. I see them as walled in, but from their perspective the Google ecosystem is all there is to the internet.
