     One evening in February 2007, a student named Paula Ceely brought her car to a stop on a remote road in

Wales. She got out to open a metal gate that blocked her path. That's when she heard the whistle sounded by

the driver of a train. Her Renault Clio was parked across a railway line. Seconds later, she watched the train

drag her car almost a kilometre down the railway tracks.

     Ceely's near miss made the news because she blamed it on the GPS (导航仪). She had never driven the

route before. It was dark and raining heavily. Ceely was relying on her GPS, but it made no mention of the

crossing. "I put my complete trust in the device and it led me right into the path of a speeding train," she told

the BBC.

     Who is to blame here? Rick Stevenson, who tells Ceely's story in his book When Machines Fail Us, points

the finger at the limitations of technology. We put our faith in digital devices, he says, but our digital helpers

are too often not up to the job. They are filled with small problems. And it's not just GPS devices: Stevenson

takes us on a tour of digital disasters involving everything from mobile phones to wireless keyboards.

     The problem with his argument in the book is that it's not clear why he only focuses on digital technology,

while there may be a number of other possible causes. A map-maker might have left the crossing off a paper

map. Maybe we should blame Ceely for not paying attention. Perhaps the railway authorities are at fault for

poor signaling system. Or maybe someone has studied the relative dangers and worked out that there really

is something specific wrong with the GPS equipment. But Stevenson doesn't say.

     It's a problem that runs through the book. In a section on cars, Stevenson gives an account of the advanced

techniques that criminals use to defeat computer-based locking systems for cars. He offers two independent

sets of figures on car theft; both show a small rise in some parts of the country. He says that once again not

all new locks have proved reliable. Perhaps, but maybe it's also due to the shortage of policemen on the streets.

Or changing social circumstances. Or some combination of these factors.

     The game between humans and their smart devices is amusing and complex. It is shaped by economics and

psychology and the cultures we live in. Somewhere in the mix of those forces there may be a way for a wiser

use of technology.

     If there is such a way, it should involve more than just an awareness of the shortcomings of our machines.

After all, we have lived with them for thousands of years. They have probably been fooling us for just as long.
