Slate Technology

In the early 20th century a new forensic technique—fingerprinting—displaced a cruder form of identification based on body measurements. Hailed as modern, scientific, and infallible, fingerprinting was adopted around the world. But in recent years doubts have been cast on its reliability, and a new technique—DNA profiling—has emerged as the forensic gold standard. In assuming it is infallible, are we making the same mistake again?

For thousands of years we sailed our cargo across oceans using zero-emission, 100 percent renewable wind. Then we switched to ships that run on oil, creating a global maritime fleet that pumps greenhouse gases into the sky. Could we go back to wind-powered ships by rediscovering a clever nautical innovation that we abandoned a century ago?

The Renaissance scholars couldn’t keep up with new information (“Have you read the latest Erasmus book?” “I don’t have time!”) and needed a better way to organize it. Thus came the invention of tables of contents, indexes, book reviews, encyclopedias, and other shortcuts. What kinds of technological solutions might help us cope with the information overload we all experience today? Guests include: Stewart Butterfield, CEO of Slack; Nathan Jurgenson, Snapchat sociologist.

Some people thought the laying of the transatlantic cable might bring world peace, because connecting humans could only lead to better understanding and empathy. That wasn’t the outcome, and recent utopian ideas about communication (Facebook might bring us together and make us all friends!) have also met with a darker reality (Facebook might polarize us and spread false information!). Should we be scared of technology that promises to connect the world? Guests include: Robin Dunbar, inventor of Dunbar’s Number; Nancy Baym, Microsoft researcher.

In the Victorian era, plaster casts became a way to preserve important artifacts in 3-D. Now, virtual reality promises to preserve places and experiences. But who decides what gets preserved? And is the technology an accurate recreation of the experience, or does it fool us into thinking we’ve encountered the real thing when we’ve done nothing of the sort? Guests include: Jaron Lanier, VR pioneer; Nonny de la Pena, VR artist; Tristram Hunt, director of the Victoria and Albert Museum.

In 1714, British parliament offered a huge cash prize to anyone who could find a way to determine longitude at sea. And it worked, sort of ... several decades later. Are modern contests (DARPA challenges, the X Prize) offering riches and glory an effective way to spur technological innovation? Guests include: Dava Sobel, author of Longitude.

In 1969, an anthropologist introduced photographs and films to people in Papua New Guinea who’d never seen themselves represented in media before. It changed their conception of the world. In modern society, social media floods us with imagery at a pace we’ve never encountered before, and powerful video manipulation technology threatens to blur the line between real and fake. Are we the new Papuans, about to be overwhelmed by a wholesale media shift? Guests include: Nathan Jurgenson, Snapchat’s in-house sociologist; Hany Farid, Dartmouth computer science professor.
