Note that Vinge described an epistemlogical singularity, beyond which reality is fundamentally unpredictable.

He used that as a justification for introducing fantastical plot elements to his writing, but his underlying reasoning was sound -- http://ciar.org/ttk/techsing/vinge.html

Given that, we would expect an encroaching singularity to cause the world to be increasingly unpredictable and harder to control, as your exertions interact with increasingly unpredictable forces working at odds to your agenda.

It takes very little reflection to confirm that, yes, the world has become a less predictable place, particularly in the last twenty years. It has become so in no small part due to technological advances.

By way of illustration, consider the following dynamic:

There is a tech company, "A", which is constantly developing better technology to sell to a customer, "B", who is using it to do something to you, "C" -- perhaps it's marketing technology for selling you bon-bons, or perhaps it's propaganda technology for advocating a political party, or perhaps it's spyware for figuring out your deepest secrets. The exact form of the technology doesn't matter for this illustration.

Every twelve months, "A" doubles the effectiveness of this technology (following the exponential trend of improving technologies in general) and six months later they sell it to "B", who starts using it on you "C" immediately, but it takes another twelve months after that for you to become aware of "A"'s technological advances through the media.

What is the visibility of that technology, from the perspectives of A, B and C? Let's map it out, with "1" representing the effectiveness of the technology when it is first available to market on January 1st of year 2000:

Do you see what's happening? By the time you become aware of the kinds of technology being used against you, the people using it against you are already using technology twice as effective, and the people developing that technology might possess technology four times as effective.

That's just as a ratio. If you look at the absolute difference between the technology you're aware of and the technology being used against you, that difference is increasing exponentially.

This can be generalized to any circumstance where familiarity with technology takes a longer path through some social networks than others. Someone communicating with someone closer to the source of the technology (say, chatting about work with the developers on IRC) will become aware of it sooner than someone reading Reddit (say, r/Futurology), and someone watching news on the television will become aware of it later still.

This, despite that all three of these kinds of people might fall under the influence of that technology at the same time.

The take-away here is that the absolute difference in effectiveness between the technology you are aware of and the technology influencing your life is growing exponentially. So is the difference between the technology you are aware of and the technology someone following different information channels is aware of.

That looks exactly like a epistemological singularity to me.
