Who would honestly ever want a device that does something like this? Do these types of cameras already exist?
I understand the idea of the article is probably more to promote imagination of the ideas of how to share, but at the same time I just can't imagine a world where everyone is sharing that much quantum aspects of their lives.
Personally, I imagine it going towards that direction then seeing some sort of "privacy disaster events" that shake up how people see privacy. Then, after those events, people really rethink their usage and change how/what they share. I'm not sure what those events would be, but I imagine them being even bigger than some of the privacy issues we have already seen as of late.
I also hope that IS what happens (it doesn't get to that much sharing), because at the end of the day, I honestly don't care what everyone is doing (literally) every second of the day. Or as Sambdala said in another comment, who has time to go through all of that?
Assume these cameras that takes photos every X seconds (probably checking e.g. pulse/blood pressure to increase/decrease X or going into video mode).
Personal violence will be hard to get away with, for instance. People acting bad will end up on Youtube much more (combine that with face recognition). And so on.
Personally, from future hardware I want a better HUD combined with good chording keyboard -- to run Emacs from the beach.
I don't have time enough to live my own life let alone comb through 1920 photos a day from every one of my friends.
I think your question shows you're missing the point, but I could very likely be wrong: the way this sharing is going to happen isn't in ways we currently see or understand. It's going to be different.
It's understandable that people think Zuck is saying people will share 1000x more on Facebook using Facebook the way Facebook currently exists, but that's not it at all.
