As technology changes we often lose something but we gain a great deal more. The word processor is one of the most powerful tools to come out of computing. Many people need to separate the assembling of their argument from arranging the presentation. One extreme example of this are dyslexics. To be able to set down headings as we identify them, then expand and work on different sections, move paragraphs around, recast sentences and polish the result is an invaluable asset to help us express the thoughts and ideas we are trying to communicate as accurately as possible.
Word processors are a wonderful way to learn to write good English.
Spell-checkers help the very young to become familiar with correct spelling. Grammar-checkers are progressively more robust and encourage young people to learn their language in exactly the way they learn from their elders and their peers. They see and hear the right forms and copy them. Very few people nowadays could contemplate writing an important text straight down with a pen in one long linear stream without the benefit of editing. It is extremely serious that this technology is not more widely used in schools to help the next generation, especially those who are not naturally literate.
