Storing feeds of each camera is got to be expensive. I thought about recording my life. It would be too expensive for me to do surveillance on myself 24/7 and then do analysis on the feeds. And i make more than the median Chinese or american.
The government doesn't need to store the video, just the processed data, such as each person's history of locations, emotional states, interactions, and actions. Analysis is automated and thus scalable to the entire country. The underlying technology improves exponentially, so everyone underestimates the social impact that this will have in a decade.
So you agree storing 24/7 video on a billion people is not practical today. I don’t think processing is practical either. Processed output can be bigger than source depending on what you want to do and doesn’t remove the need to store original data to get value out of it always.
Technology has improved exponentially in the past. No guarantee it will continue. Ram prices are double from a year ago. Gpu prices are also not much better than 2 years ago.
I gave specific examples of processed outputs that are much smaller than source and are trivial to store today. No need to store the source video. For an example of what you can do with location history, see https://kieranhealy.org/blog/archives/2013/06/09/using-metad...
