Charlie 13: http://futurestates.tv/episodes/charlie-13%20 (Actually I didn't watched this video, it was loading too slow and there was no option to change video quality)
First two videos are advertisings from different companies (Corning and Microsoft). The technology represented in A Day Made of Glass seems to be more innovativ. In one book about advertising (I cannot find the source now) I've read the following: The most succesfull advertising of PC for private users when companies only started to sell them in US was not "They will make your life easy" or "The technology will fully cange your life". The most successfull advertising was something like "Our PC wouldn't actually change your life". Is this story true or not, Productivity Future Vision represents the same approach: People are the same, the stereotypes are the same (like the man in taxi, or the girl asking her mother about recipe, or the meeting). The procedures, the situations are the same, only with better special effects.
A Day Made of Glass is a bit different. Here technologies are deeper integrated into people's lifestyle. So there are more changes, related to them. Technology starts to change the way of work or study. I like how study is represented here - children can get information wherever they want, and this information is represented not only as some theoretical knowledge, but as different visual content, even 3D. In general the accent is moved from textual to visual content, in all areas of life, and this is representation of some changes in people's mind.
Plurality resembled for me a Little Brother book, which I have read before (it's also about a world of total control, like the Grid in this video, and teenagers fighting against this system). I think this video shows dystopian society. But the problem isn't in technology itself. I don't see a problem when somebody knows what books do I like or what food do I buy. But it becomes to a problem when it's forbidden to read certain books for example. I think every thing can be misused, every element of technology in general meaning, since first people used stones to kill people of other tribe, instead of building house of that stones. So it's nothing unusual when such technologies like GRID can be used to control people. The only thing is, when our world becomes more globalized and technology develops further, this problems becomes more and more clearer and unavoidable.
I would like to point, that in Plurality, in Charlie 13 and in Little Brother we see how teenagers try to do something against system. And this is why I'm optimistic. If technology develops further and new devices and gadgets etc. appear, teenagers (as digital natives) will always know it better than elder people (as digital immigrants).So they will have chance to cheat the system, to jam scanners etc. And this is why I think that every dystopia cannot exist forever. (and it is not about revolution, it is mostly about "silent revolution", when people just ignore the system). But it is already another story...
