Two new books offer complementary visions of how society is being reshaped by those who build, use and manage AI. In The Alignment Problem, writer Brian Christian gives an intimate view of the people making AI technology -- their aims, expectations, hopes, challenges and desolations. Starting with Walter Pitts's work on a logical representation of neuron activity in the early twentieth century, he recounts the ideas, aims, successes and failures of researchers and practitioners in fields from cognitive science to engineering. Atlas of AI, from the influential scholar Kate Crawford, deals with how, practically, AI gets into and plays out in our lives.

The US labor market looks markedly different today than it did two decades ago. It has been reshaped by dramatic events like the Great Recession but also by a quieter ongoing evolution in the mix and location of jobs. In the decade ahead, the next wave of automation technologies may accelerate the pace of change. Millions of jobs could be phased out even as new ones are created. More broadly, the day-to-day nature of work could change for nearly everyone as intelligent machines become fixtures in the American workplace. Until recently, most research on the potential effects of automation, including our own, has focused on the national-level effects. Our previous work ran multiple scenarios regarding the pace and extent of adoption. In the midpoint case, our modeling shows some jobs being phased out but sufficient numbers being added at the same time to produce net positive job growth for the United States as a whole through 2030.

At first, technologists issued dystopian alarms about the power of automation and artificial intelligence (AI) to destroy jobs. Then came a correction, with a wave of reassurances. Now, the discourse appears to be arriving at a more complicated understanding, suggesting that automation will bring neither apocalypse nor utopia, but instead both benefits and stress alike. Such is the ambiguous and sometimes disembodied nature of the "future of work" discussion. Hence the analysis presented here.
