In the early days of the internet, many people worried that as people in the rich world embraced new computing and communications technologies, people in the poor world would be left stranded on the wrong side of a "digital divide." Yet the debate over the digital divide is founded on a myth that plugging poor countries into the internet will help them to become rich rapidly.
This is highly unlikely, because the digital divide is not a problem in itself, but a symptom of deeper, more important divides: of income, development and literacy（识字）. Fewer people in poor countries than in rich ones own computers and have access to the internet simply because they are too poor, are illiterate, or have other more immediate concerns, such as food, health care and security. So even if it were possible to wave a magic wand（棒） and cause a computer to appear in every household on earth, it would not achieve very much: a computer is not useful if you have no food or electricity and cannot read. Yet such Wand-waving - through the construction of specific local infrastructure（基础设施） projects such as rural tele-centers--is just the sort of thing for which the UN's new fund is intended.
This sort of thing is the wrong way to go about addressing the inequality in access to digital technologies: it is treating the symptoms, rather than the underlying（下面） causes. The benefits of building rural computing centers, for example, are unclear. Rather than trying to close the divide for the sake of it, the more sensible goal is to determine how best to use technology to promote bottom-up development. And the answer to that question turns out to be remarkably clear: by promoting the spread not of PCs and the Internet, but of mobile phones.
