HOW TO CREATE A MIND

THE SECRET OF HUMAN THOUGHT REVEALED

A pioneering developer of optical character recognition and text-to-speech software explores the possibility of creating a synthetic neocortex that could surpass the human mind.

Kurzweil (The Singularity Is Near: When Humans Transcend Biology, 2005, etc.) bases his prediction on modern insights into how the brain has evolved a hierarchical pattern-recognition structure. We perceive the bare outline of events and reconstruct memories in an ordered sequence, and our ability to fill in the blanks provides the foundation for conscious experience. “We are constantly predicting the future and hypothesizing what we will experience,” writes the author. “This expectation influences what we actually perceive.” Kurzweil estimates that at birth, the neocortex contains 300 million pattern processors connected horizontally and vertically, which allow us to connect patterns. In his opinion, it is these processors, rather than the neurons of which they are composed, that are the fundamental units of the neocortex. They allow us to fill out an increasingly complex picture of reality, enabling us to rapidly evaluate our environment and then confirm our hypothesis by checking out the details. Then we are able to respond rapidly to changes in our environment by creating new technologies. Why not create a synthetic extension of our brain using advanced computer technology? It could “contain well beyond a mere 300 million processors,” perhaps as many as a billion or a trillion. Our dependence upon search engines and other technology is a harbinger of a future in which we will not only outsource information storage but directly enhance our mental functioning. In a parallel development, Kurzweil and other software developers are designing more advanced computers based on complex modular functioning.

A fascinating exercise in futurology.

WHEN BREATH BECOMES AIR

A neurosurgeon with a passion for literature tragically finds his perfect subject after his diagnosis of terminal lung cancer.

Writing isn’t brain surgery, but it’s rare when someone adept at the latter is also so accomplished at the former. Searching for meaning and purpose in his life, Kalanithi pursued a doctorate in literature and had felt certain that he wouldn’t enter the field of medicine, in which his father and other members of his family excelled. “But I couldn’t let go of the question,” he writes, after realizing that his goals “didn’t quite fit in an English department.” “Where did biology, morality, literature and philosophy intersect?” So he decided to set aside his doctoral dissertation and belatedly prepare for medical school, which “would allow me a chance to find answers that are not in books, to find a different sort of sublime, to forge relationships with the suffering, and to keep following the question of what makes human life meaningful, even in the face of death and decay.” The author’s empathy undoubtedly made him an exceptional doctor, and the precision of his prose—as well as the moral purpose underscoring it—suggests that he could have written a good book on any subject he chose. Part of what makes this book so essential is the fact that it was written under a death sentence following the diagnosis that upended his life, just as he was preparing to end his residency and attract offers at the top of his profession. Kalanithi learned he might have 10 years to live or perhaps five. Should he return to neurosurgery (he could and did), or should he write (he also did)? Should he and his wife have a baby? They did, eight months before he died, which was less than two years after the original diagnosis. “The fact of death is unsettling,” he understates. “Yet there is no other way to live.”

A moving meditation on mortality by a gifted writer whose dual perspectives of physician and patient provide a singular clarity.

Occasionally wonky but overall a good case for how the dismal science can make the world less—well, dismal.

GOOD ECONOMICS FOR HARD TIMES

“Quality of life means more than just consumption”: Two MIT economists urge that a smarter, more politically aware economics be brought to bear on social issues.

It’s no secret, write Banerjee and Duflo (co-authors: Poor Economics: A Radical Rethinking of the Way To Fight Global Poverty, 2011), that “we seem to have fallen on hard times.” Immigration, trade, inequality, and taxation problems present themselves daily, and they seem to be intractable. Economics can be put to use in figuring out these big-issue questions. Data can be adduced, for example, to answer the question of whether immigration tends to suppress wages. The answer: “There is no evidence low-skilled migration to rich countries drives wage and employment down for the natives.” In fact, it opens up opportunities for those natives by freeing them to look for better work. The problem becomes thornier when it comes to the matter of free trade; as the authors observe, “left-behind people live in left-behind places,” which explains why regional poverty descended on Appalachia when so many manufacturing jobs left for China in the age of globalism, leaving behind not just left-behind people but also people ripe for exploitation by nationalist politicians. The authors add, interestingly, that the same thing occurred in parts of Germany, Spain, and Norway that fell victim to the “China shock.” In what they call a “slightly technical aside,” they build a case for addressing trade issues not with trade wars but with consumption taxes: “It makes no sense to ask agricultural workers to lose their jobs just so steelworkers can keep theirs, which is what tariffs accomplish.” Policymakers might want to consider such counsel, especially when it is coupled with the observation that free trade benefits workers in poor countries but punishes workers in rich ones.

Occasionally wonky but overall a good case for how the dismal science can make the world less—well, dismal.
