There's a book called Opt-Out from Rory Price about a future where humanity starts using AR more and more to the point that it's almost obligatory to have a device of this kind for everything, even as ID. It then talks about a group that develops a free/libre version of this device's OS and they have to decide about personal issues or try to maintain their views. It's entertaining and not too long, but I think it shows a very possible future.

I haven't heard from its author in some time, but I think they discovered they were someone else too ;), that's why I love this book.
