Although sometimes too abstruse, this is mostly a surprisingly lucid introduction to techniques that are making computers...
A nonmathematical yet still somewhat technical explanation of how researchers are going about achieving artificial intelligence.
This is not another cheerful or alarming exercise in futurology. Science writer Mitchell (Computer Science/Portland State Univ.; Complexity: A Guided Tour, 2011, etc.) begins by wondering if an intelligent machine would “require us to reverse engineer the human in all its complexity or is there a shortcut, a clever set of yet unknown algorithms, that will produce what we recognize as full intelligence.” She then explains what researchers have done so far. Beginning in the 1950s, when success seemed just around the corner, there was symbolic AI, which involved programmers using symbols that humans could understand to solve straightforward logical problems. This led to “expert systems,” which used massively detailed instructions to make decisions in narrow fields such as disease diagnosis better than human experts. By the 1980s, the limitations of AI became more obvious. Today, concepts such as “deep learning,” relying on artificial neural networks, evaluate information without following rigid instructions. Despite the name and hype (and accomplishments—e.g., being unbeatable at Jeopardy), machine and human learning are not comparable. Highly advanced computers are “trained” by immense inputs, made possible only with the advent of 21st-century “big data.” After evaluating their outputs, programmers retrain them to improve their accuracy. Like humans, they are not perfect. Mitchell maintains that true superintelligence will not happen until machines acquire human qualities such as common sense and consciousness. These are nowhere in sight despite recent spectacular advances—in translation, facial recognition, etc.—and the author believes that this absence makes it unlikely that one anticipated breakthrough, true driverless cars, will happen any time soon. “It’s worth remembering,” she writes, “that the first 90 percent of a complex technology project takes 10 percent of the time and the last 10 percent takes 90 percent of the time.”

A forceful, necessarily provocative call to action for the preservation and protection of American Jewish freedom.
Known for her often contentious perspectives, New York Times opinion writer Weiss battles societal Jewish intolerance through lucid prose and a linear playbook of remedies.
While she was vividly aware of anti-Semitism throughout her life, the reality of the problem hit home when an active shooter stormed a Pittsburgh synagogue where her family regularly met for morning services and where she became a bat mitzvah years earlier. The massacre that ensued there further spurred her outrage and passionate activism. She writes that European Jews face a three-pronged threat in contemporary society, where physical, moral, and political fears of mounting violence are putting their general safety in jeopardy. She believes that Americans live in an era when “the lunatic fringe has gone mainstream” and Jews have been forced to become “a people apart.” With palpable frustration, she adroitly assesses the origins of anti-Semitism and how its prevalence is increasing through more discreet portals such as internet self-radicalization. Furthermore, the erosion of civility and tolerance and the demonization of minorities continue via the “casual racism” of political figures like Donald Trump. Following densely political discourses on Zionism and radical Islam, the author offers a list of bullet-point solutions focused on using behavioral and personal action items—individual accountability, active involvement, building community, loving neighbors, etc.—to help stem the tide of anti-Semitism. Weiss sounds a clarion call to Jewish readers who share her growing angst as well as non-Jewish Americans who wish to arm themselves with the knowledge and intellectual tools to combat marginalization and defuse and disavow trends of dehumanizing behavior. “Call it out,” she writes. “Especially when it’s hard.” At the core of the text is the author’s concern for the health and safety of American citizens, and she encourages anyone “who loves freedom and seeks to protect it” to join with her in vigorous activism.

Review Posted Online: Aug. 22, 2019
Bernstein and Woodward, the two Washington Post journalists who broke the Big Story, tell how they did it by old fashioned seat-of-the-pants reporting — in other words, lots of intuition and a thick stack of phone numbers. They've saved a few scoops for the occasion, the biggest being the name of their early inside source, the "sacrificial lamb" H**h Sl**n. But Washingtonians who talked will be most surprised by the admission that their rumored contacts in the FBI and elsewhere never existed; many who were telephoned for "confirmation" were revealing more than they realized. The real drama, and there's plenty of it, lies in the private-eye tactics employed by Bernstein and Woodward (they refer to themselves in the third person, strictly on a last name basis). The centerpiece of their own covert operation was an unnamed high government source they call Deep Throat, with whom Woodward arranged secret meetings by positioning the potted palm on his balcony and through codes scribbled in his morning newspaper. Woodward's wee hours meetings with Deep Throat in an underground parking garage are sheer cinema: we can just see Robert Redford (it has to be Robert Redford) watching warily for muggers and stubbing out endless cigarettes while Deep Throat spills the inside dope about the plumbers. Then too, they amass enough seamy detail to fascinate even the most avid Watergate wallower — what a drunken and abusive Mitchell threatened to do to Post publisher Katherine Graham's tit, and more on the Segretti connection — including the activities of a USC campus political group known as the Ratfuckers whose former members served as a recruiting pool for the Nixon White House. As the scandal goes public and out of their hands Bernstein and Woodward seem as stunned as the rest of us at where their search for the "head ratfucker" has led. You have to agree with what their City Editor Barry Sussman realized way back in the beginning — "We've never had a story like this. Just never."
