That still leaves my first question regarding observer effects and how people would respond to such a technology on an individual level. It would have the capacity to reshape behaviour towards preferential and/or optimal interactions, would it not? Seeing how we do not want reinforce models with 'erroneous' interactions?
You are persistently surveilled in London and Shanghai and New York City - yet people act just as unhinged in ways they did before cameras were installed.
I'm not sure what other data acquisition/technology arc is possible though, and open to ideas.
Unhinged people do, but ordinary people? I'd be willing to bet that normal people who are in areas where they are aware they're on camera don't behave as their normal selves. It's hard to see how it could be otherwise.
