Google for the Brain


A colleague of mine, Scott Coughlin, established a blog called a IT Thought of the Day. Afer reading an article in today's USA today about "augmented reality", here is my thought- coupling a Google for the brain with “augmented reality”.
How often have you recognized someone, but forgot their name ? Although this by itself may be embarrassing, memory loss can obviously have more dire consequences. Our brain is a sponge that absorbs a lot of information starting at an early age. Would it not be useful to be able to recall what is locally stored? Indeed, I find myself using Google to seek information about stuff that I was taught in school, but have forgotten. According to Gary Marcus, professor of psychology at New York University, “What we remember at any single moment depends heavily on the accidents of which bits of mental flotsam and jetsam happen to be active. Our mood, our environment, even our posture can influence our delicate memories.” Making our memories more accurate and more accessible would require a Google-like search engine which combines cue-driven promptings similar to human memory with the location-addressability of computers. Furthermore, there's no reason in principle why neural prosthetics could not incorporate this sort of functionality.
To take this one step further, you could upload this memory bank information to a smartphone which combines a camera, GPS and web access. The phone's camera can already "recognize" an object or place that a user is pointing to by overlaying the screen's image to location data. The travel industry is starting to exploit this new "augmented reality" technology to give tourist-friendly information about restaurants, sights and shops. This information could readily be displayed on the heads-up display of the wearer’s glasses. Imagine while you are talking to someone you have access to all his public information (e.g. Facebook etc.) and all the information that was shared in previous conversations or observations. A more far-future neural prosthetic might actually have a direct neural linkup to your brain, allowing you to see Google results on your retina. If everybody were on Facebook, we could know anybody’s name that we saw on the street – and more.
Opposing viewpoints about whether having a Google brain is a good thing or bad thing are discussed in Discover magazine's Google is Making Us Smarter and Atlantic Monthly's Is Google Making Us Stupid?.
There are additional cons. One issue that will have to be resolved is the downside of surfacing repressed memories which are usually traumatic in nature and block a painful time in one’s life. Another issue is that in general our Google brains also are changing to become overly dependent on the rewards of the Internet. According to neuroscientists stopping this frequent self-directed intellectual stimulation, may become hard to stop. Not only does this result in less downtime for our brains, but it also can lead to exhaustion. Many studies have shown how important downtime in the brain is for creative thinking, working memory in general, all complex problem solving, and of course, error detection.
After all, when we recognize someone we want to actually get their name right.

Maritime Domain Awareness at a nexus

Recent piracy activity calls attention to the notion that today’s interdependent global economy depends on the free and uninterrupted use of the sea. Not only is the U.S. Navy well positioned to help other maritime forces and organizations maintain an orderly maritime domain, the enabler of Maritime Domain Awareness is critically positioned at the nexus of the technological and cultural implications of networking; the renewed impetus for data sharing across government and non-governmental organizations; and the general goodwill for building maritime partnerships.

Networking
Networking and social networking, in particular, are the astonishing phenomena of our time. Conventional wisdom is that the value of a network is demonstrated by Metcalfe's Law (a network grows in proportion to the square of the number of users). However, Reed’s Law argues that Metcalfe actually understates the potential value of the network, because the real power of the network is not n² but 2n, which is a number that gets large very fast. Ipso facto if Facebook was a country it would be the 4th largest country in the world.As digital networking brings scale and global reach to all aspects of our lives and activities, established processes will adapt and evolve. Collaboration will replace structural impediments that often exclude valuable contributions. Wikipedia is an example of collaboration - small contributions/comments become a resource for all to use. Clay Shirky who focuses on the rising usefulness of decentralized technologies (and recently cited by ADM Stavridis) argues convincingly, that even though hierarchical organizations are established for the purpose of efficiently allocating resources and achieving goals, they are inherently inefficient and self-limiting. Networks can be an alternative to centralized and institutional structures. Consequently, legacy models of authority based on personal or institutional authority are evolving to what is termed algorithmic authority. This refers to regarding as authoritative the unmanaged process of extracting value from material from multiple sources - sources themselves that are not universally vetted for their trustworthiness. Trust comes from producing good results (Wikipedia), or when people trust others (eBay). A key enabler of Maritime Domain Awareness is a robust network that allows for information to be accessible, usable and sharable.

Info Sharing
Recently, after the attempt to bring down a Detroit-bound flight on December 25, the White House reiterated its information sharing policy. Although the 9/11 commission famously concluded that authorities did not “connect the dots”, the case for more information sharing got more impetus last Christmas. To highlight a new era of open Government, President Obama on his first day in office directed all agencies to adopt a presumption in favor of disclosure .Likewise gaining momentum is the unifying concept of information sharing for maritime security partnerships and for good reason. According to the Naval Studies Board, “A comprehensive MDA system would permit identification of threatening activities and anomalous behavior. Achieving such a system where it does not now exist—and strengthening it where there is already a foundation—must be viewed as a critical step in building regional partnerships.”Some regions already have established MDA information sharing networks, some examples being the Malacca Strait Security Initiative partnering Singapore, Indonesia, and Malaysia; the Gulf of Guinea network; the Joint Interagency Task Force-South that addresses concerns in the Caribbean region and the Virtual Regional Maritime Traffic Center - Americas (VRMTC-A) in Latin America.Good enough, but the diversity and complexity of interests in the maritime domain require an outreach to additional entities: law enforcement agencies, local civil authorities, commercial and nongovernmental actors, like shipping and insurance companies.The downside of collecting all this flood of information (estimated at 1,200 exabytes) is the challenge of analyzing the data to spot patterns and extract useful information.There are policy issues. Critics perceived President Obama's plan for "knowledge discovery," as a revival of the controversial data-sifting program that the Bush administration launched after the 9/11 terrorist attacks. A recent Economist article on the deluge of all this data points out that the potential for good depends on making the right choices about when to restrict the flow of data – and when to share it.
From a technical standpoint, the Navy’s emphasis and investment in Maritime Fusion and Analysis Services recognizes the challenge of finding the needle in the haystack. Using rules derived by crunching through billions of transactions, credit-card companies have led the way in their ability to monitor purchases and identify fraudulent ones with a high degree of accuracy (e.g. stolen credit cards are more likely to be used to buy hard liquor than wine). Similarly, fundamental to maritime anomaly detections are the rule sets that trigger an alert. Developing these rule sets comes under the umbrella of Techniques, Tactics and Procedures and should be a Navy priority.

Building partnerships
The security of any country is improved by improving situational awareness of what is happening in its maritime areas. Therefore any country ought to be willing to share relevant data with those it perceives to have congruent interests. Relationship building and information sharing during normal times is likely to influence the ease and trust with which information or individuals can be accessed in a time of crisis.ADM Roughead has remarked , “You cannot surge trust because trust will underpin everything that we do. Trust does not have a switch: you can't turn it on, you can't turn it off. It is something that takes time to build and must be worked cooperatively to maintain that trust.”The success of the 19th International Seapower Symposium (ISS) at the Naval War College underscored the world's maritime services’ enthusiastic commitment to bridge regional initiatives and build a network of partnerships by linking cooperative efforts beyond and across traditional regional maritime boundaries. "I believe that we maritime service chiefs are on the cutting edge of international partnership, and I do believe that we must challenge ourselves during ISS 19 to think expansively about how our mutual efforts can safeguard international peace and prosperity in the 21stcentury," said ADM Roughead.According to the Naval Studies Board, information sharing can be facilitated through combatant maritime operations centers which develop awareness and relationships with partner nations. Exercises and exchanges build trust.The bottom line is that the pace of networking, info sharing and partnership development is accelerating. Maritime Domain Awareness is on the bow wave.
