Now... if this reduces our exposure to x-rays and allows the TSA to tamp down the aggravation at airports, you can expect the new systems to have their upside. On the other hand, this sort of thing could be Big Brother's most delicious dream. (More on that aspect.)
...then there's this. Cell phone providers received 1.3 million cell phone snooping requests last year from law enforcement agencies seeking information on locational data and calling records. There is little oversight over who can make such requests, or what is done with the information.
Way back in '97, in The Transparent Society: Will Technology Force us to Choose between Privacy and Freedom, I made it clear that we'll not stop any of this with whining, moaning or by trying to ban these technologies. Our only chance? If government - and other mighty elites - are absolutely fated to know everything about us anyway, our sole option is to know everything about them.
This is the important distinction between surveillance and sousveillance -- looking down vs. looking back.
And though I've covered it at-length from many directions, I expect to be doing so repeatedly, for the rest of my life.
Is it even remotely possible for sousveillance to work? For citizens to shine enough light upward to remind our civil servants that they are servants? To keep a choke-chain on our guard dogs, so they never see themselves as wolves? To remind corporations that they are constructs, and oligarchs that they are not feudal lords, with droit du seigneur? As it happens, there are dozens of techniques that might help... providing we nurture the calm, rational... but militant... determination to make this practically happen.
Let's start simple. See just one practical approach that - with a very simple slip of legislation that could be written on one piece of paper - and maybe cost 20 million dollars - we might suddenly and smoothly add a layer of safety and accountability to help let us sleep at night. It's no panacea! But by simply changing how government inspectors general function, we might follow the sage advice of Sun Yat Sen and stymie the bad in government, while aiding the good.
Let's hope that this election cycle someone actually listens.
And another Transparency related item. This one not only forecast in The Transparent Society but also in EARTH...
Indeed. And then comes the new world of "augmented reality."
Patricia F. Anderson wrote: "Graffiti goes virtual with an augmented reality app for your cell phone, called LZRTAG Shades of @DavidBrin 's early scenes in Existence." Indeed, the layering of virtual surfaces over our world has already begun. Still images, animations and video can be tagged to real world surfaces, so your smartphone can interact with media, billboards, lampposts or landmarks. Vernor Vinge and I do - however - show where it must eventually lead. That is, where it must lead if we are lucky and do smart things!
To see where it will lead if we drop courage and brains? Try Nineteen Eighty-Four.
=== Fascinating cases of watching the watchers at work ===
Think I am naive? Teams at Harvard and the University of Hong Kong have been using new software that allows them to watch the censoring of posts on Chinese social-media sites more closely than before. Monitoring the Monitors summarizes their report in The Economist:
The team found that, overall, 13% of all social media posts in China were censored. Yet their most surprising result is that posts critical of the government are not consistently censored. On the other hand, posts urging people to assemble in protest, are generally removed from the internet within hours. Harvard professor Gary King writes, “Clearly the goal is actually to repress people gathering.”
The researchers analyzed the posts that had been censored to determine exactly what had made them objectionable to the government. What they found was a constantly changing list of keywords and sensitive topics, resulting in "a cat-and-mouse contest between people and censors.”
=== Keep the dream alive ===
On the recent American Independence Day... with a marathon of the eponymous film playing in the background ... I was reminded of the ways that our revolution has affected the world. Sometimes for ill - though less than any other great "pax" power across time. And sometimes for profound good. That may be viewed as biased (though in fact, I am more of a Californian than a yankee). So I suggest steeping in points of view that might be considered neutral and yet poetically insightful. Such as this account, by the great Russian novelist Leo Tolstoy, of how a remote Circassian mountain tribe once sat at his feet, demanding stories about ... Abraham Lincoln.

Wake up and end it. By winning it.
=== Science Miscellany ===
We need to discuss what to do about nuclear waste. It never made the slightest sense for us to abandon the Yucca Mountain site on account of some supposed small chance that the depository might leak a little in 10,000 years. Say what? So these people are now willing to talk about sci fi levels of time, when they won’t even discuss a decade from now, on any other issue? Dig it. In 10,000 years, the stored radionuclides are far more likely to be more valuable as stored "gold", than they are to leak into a desert aquifer. Read up.
Dinosaur sex! Scientific! With feathers, yet. And facial expressions.
