I was going to include a number of quotes to illustrate the article but, basically, if you are interested in this area you should read this.
This is a series of articles collected into a special section (they call it a “deep dive”.) A lot of ideas and possible use cases. More of these on different subjects would be welcome.
It’s in the July 2013 edition of Wired UK. There’s no link yet, so go buy a copy.
