“We’re working on constantly shifting grounds,” said Rudolf Frieling, a curator of media arts at the San Francisco Museum of Modern Art, which has been at the forefront of sustaining online art. “Whatever hardware, platform or device we’re using is not going to be there tomorrow.”

“Frankly speaking,” he added, “it’s a huge challenge.

Not every museum is set up to do that. It takes huge technical expertise.” The riddles are only solved by “actually doing it,” Mr. Frieling explained.

We live in a world made up more of story than stuff. We are creatures of memory more than reminders, of love more than likes. Being attentive to the needs of others might not be the point of life, but it is the work of life. It can be messy, and painful, and almost impossibly difficult. But it is not something we give. It is what we get in exchange for having to die.

This book is a balefully seminal work in which neither author has the language to see, much less to express, the titanic centralizing evil they are constructing. “What Lockheed Martin was to the 20th century,” they tell us, “technology and cybersecurity companies will be to the 21st.” Without even understanding how, they have updated and seamlessly implemented George Orwell’s prophecy. If you want a vision of the future, imagine Washington-backed Google Glasses strapped onto vacant human faces — forever. Zealots of the cult of consumer technology will find little to inspire them here, not that they ever seem to need it. But this is essential reading for anyone caught up in the struggle for the future, in view of one simple imperative: Know your enemy.

But there is a dark side. Big data erodes privacy. And when it is used to make predictions about what we are likely to do but haven’t yet done, it threatens freedom as well. Yet big data also exacerbates a very old problem: relying on the numbers when they are far more fallible than we think. Nothing underscores the consequences of data analysis gone awry more than the story of Robert McNamara.
