Electric Machines

Computers have changed since 1981, when Tracy Kidder memorably recorded the drama, comedy, and excitement of one company's efforts to bring a new microcomputer to market. What has not changed is the feverish pace of the high-tech industry, the go-for-broke approach to business that has caused so many computer companies to win big (or go belly up), and the cult of pursuing mind-bending technological innovations.

For centuries, electricity was seen as little more than a curious property of certain substances that sparked when rubbed. Then, in the 1790s, Alessandro Volta began the scientific investigation that ignited an explosion of knowledge and invention. The force that once seemed inconsequential was revealed to be responsible for everything from the structure of the atom to the functioning of our brains. In harnessing its power, we have created a world of wonders—complete with roller coasters and radar, computer networks and psychopharmaceuticals.

In late 1997, a runaway teenager and her small yellow toy robot travel west through a strange American landscape where the ruins of gigantic battle drones litter the countryside, along with the discarded trash of a high-tech consumerist society addicted to a virtual-reality system. As they approach the edge of the continent, the world outside the car window seems to unravel at an ever faster pace, as if somewhere beyond the horizon, the hollow core of civilization has finally caved in.

Analyzing brainwaves, the imperceptible waves of electricity surging across your scalp, has been possible for nearly a century. But only now are neuroscientists becoming aware of the wealth of information brainwaves hold about a person’s life, thoughts, and future health. From the moment a reclusive German doctor discovered waves of electricity radiating from the heads of his patients in the 1920s, brainwaves have sparked astonishment and intrigue, yet the significance of the discovery and its momentous implications have been poorly understood.

In this accessible introduction to AI, Sean O'Callaghan and Paul Hoffman explore its social and ethical impacts for ministry and teaching. The authors shed light on the biblical vision for human flourishing—and on how AI can help or hinder that flourishing. Avoiding both alarmism and uncritical acceptance, O'Callaghan and Hoffman offer resources and practical tools for using AI in our classrooms and congregations.

Leading neuroscience researchers are racing to unlock the secrets of the mind. On the cusp of decoding brain signals that govern motor skills, they are developing miraculous technologies to enable paraplegics and wounded soldiers to move prosthetic limbs, and the rest of us to manipulate computers and other objects through thought alone. These fiercely competitive scientists are vying for Defense Department and venture capital funding, prestige, and great wealth.
