Dylan Evans, The Guardian: "As our society becomes ever more dependent on information technology, the gulf between those who understand computers and those who don't will get wider and wider. In 50 years, perhaps much less, the ability to read and write code will be as essential for professionals of every stripe as the ability to read and write a human language is today. If your children's children can't speak the language of the machines, they will have to get a manual job - if there are any left."
