So what you're saying is that you want to give every crazy fuckwad who hates whites/men/fat people/bearded individuals/etc (subtract as necessary) the means by which to more efficiently single me out, find where I am in real time and harm me? You want my boss to be able to see when I told a little white lie about why I'm late, and instead of dropping off a package, I went for a nooner with the missus?
How about the details of my sex life? Should they be available to anyone who wants to attempt to embarrass me? Or my wife? Or my parents, sister, what-have-you? People in power generally don't need to abuse that power because they're already in power. Their indiscretions (at least in wealthy societies) are relatively minor. They don't generally have a reason to want to spy on the average citizen.
But the world is full of truly crazy people who absolutely do get it in their heads to harm others. White power types hunting for [insert racial epithet] here. Minorities looking for revenge. Bored bosses looking for staff to fire or jealous lovers looking for an excuse to get the partner abuse on.
If I could watch every corner in the city, what prevents me for picking a secluded neighborhood, watching every night and logging who goes by? What if I see the same female every Thursday at the same time? Couldn't I plane a rape? Or a murder?
What if I see that kid who made fun of me in school going by that one dark alley every single night as he walks home from school? Or I find that my boss always drives too fast on the rather dangerous road where spike strips could easily be places and then removed?
I don't think you understand how horrible people are. People in power don't need to resort to most of the truly sadistic and horrible stuff because they have so much power that they can do whatever they want. People without power - and that's most of us - need to do our dirty deeds either in secret, or only in our own heads.
Give these people the power to observe everything, everywhere and "in their own heads" will become "in secret" more and more often. Especially as we start to find out what is in people's heads and regulate against it! (Thanks, UK. You guys are pro.)
What % of society needs to abuse these technologies before it's no longer "okay?" What excuses will we use? Cameras are a "level playing field" because everyone watches them? How many of use watch them to catch bad guys for free? How many of us watch the spaces between the cameras? How many of us use the cameras just to catch our hated neighbor putting out one extra bag of trash?
Are all laws worth enforcing, and worth enforcing equally? If so, we're all criminals, because modern laws are designed such that you break several of them during any given day, even if you are going out of your way to be law abiding. Who runs society when we're all in jail? Who pays the fines for all minor infractions when none of us can get jobs because we all have unpaid fines?
How does our society function when every minor slight - real or imagined - can be reciprocated to with completely disproportionate surveillance-enabled retribution?
You are advocating a society in which the most devious, the most douchy and the most morally able to execute dramatic preemptive strikes wins...because everyone else absolutely will lose.
If Google can see everything I do they can advertise at me more effectively. That's not something I'm comfortable with, but it's narrow and targeted. If the NSA can see everything I do, they can make my life hell every time I try to cross the US border to go to a conference. I'm even less okay with this, but they have a lot of very big men with even larger guns.
If my neighbor or my boss can see everything I do they can ruin my life in a similarly completely legal manner. I may or may not have the time and resources to fight that war and win.
If the crazy racist down the street can see everything I do, then he might Treyvon Martin my ass...and apparently, get away with it. This is a thing that you can do now.
I don't know man, your idea of a "level" society terrifies the shit out of me. It really does.
