obsession with profit and control is the source of the error...,

THE Southwest is famously fertile territory for ghost towns. They didn’t start out depopulated, of course — which is what makes the latest addition to their rolls so strange. Starting next year, Pegasus Holdings, a Washington-based technology company, will build a medium-size town on 20 square miles of New Mexico desert, populated entirely by robots.

Scheduled to open in 2014, the Center for Innovation, Testing and Evaluation, as the town is officially known, will come complete with roads, buildings, water lines and power grids, enough to support 35,000 people — even though no one will ever live there. It will be a life-size laboratory for companies, universities and government agencies to test smart power grids, cyber security and intelligent traffic and surveillance systems — technologies commonly lumped together under the heading of “smart cities.”

The only humans present will be several hundred engineers and programmers huddled underground in a Disneyland-like warren of control rooms. They’ll be playing SimCity for real.

Since at least the 1960s, when New York’s Jane Jacobs took on the autocratic city planner Robert Moses, it’s been an article of faith that cities are immune to precisely this kind of objective, computation-driven analysis. Much like the weather, Ms. Jacobs said, cities are astoundingly complex systems, governed by feedback loops that are broadly understood yet impossible to replicate.

But Pegasus and others insist there’s now another way — that, armed with enough data and computing muscle, we can translate cities’ complexity into algorithms. Sensors automatically do the measuring for us, while software makes the complexity manageable.

“We think that sensor development has gotten to the point now where you can replicate human behavior,” said Robert H. Brumley, the managing director and co-founder of Pegasus. These days, he and others believe, even the unpredictable “human factor” is, given enough computing power, predictable. “You can build randomness in.”

Mr. Brumley isn’t alone in his faith that software can do a better job of replicating human behavior than the humans themselves. A start-up named Living PlanIT is busy building a smart city from scratch in Portugal, run by an “urban operating system” in which efficiency is all that matters: buildings are ruthlessly junked at the first signs of obsolescence, their architectural quality being beside the point.

To the folks at Living PlanIT and Pegasus, such programs are worth it because they let planners avoid the messiness of politics and human error. But that’s precisely why they are likely to fail. Fist tap Nana.
