     Please help! I live in Germany with my wife and three kids. My parents live in the UK. I want my kids

to contact with their grandparents often. The kids all use e-mail, Skype and SMS but my parents won’t. I’ve bought them a laptop, paid for broadband(宽带), given them both mobile phones and a digital

camera, but they won’t use them. My parents say they hate computers and new technology. What can I do with these technophobes

     Actually, the original technophobes were the Luddites, a group of cloth workers in 19th century Britain during the Industrial Revolution. The Luddite cloth workers, who traditionally made cloth by hand, were

worried that machines were going to take away their jobs and way of life. These machines could make

cloth much faster and cheaper than humans. In 1811 and 1812 the Luddites destroyed the machines, but

the British government supported the factory owners. Many Luddites were arrested. Charlotte Bronte’s

novel Shirley will tell your parents all about it.

     Laura makes some interesting points, I think. Technophobes has been a common theme in science

fiction. Frankenstein, one of the first science fiction, is a warning of what could happen if humans began to experiment with human life.

     One thing you could try is to find hardware that is designed for older people to use. An example is the mobiles made by the US company, Jitterbug. Instead of icons(图标) and menus the Jitterbug phones ask users simple “yes/no” questions and have larger keypads. The company realized that there are potentially 100 million older users in the US alone.
