O’Reilly author and ETel regular Brian McConnell has just published a thought provoking essay, The End Of The Language Barrier. Brian is the the leader of the Worldwide Lexicon project, which we’ve highlighted here before. He predicts that the language barrier, at least for published content, will be history in less than three years. In his essay, he argues that the real breakthrough is social, not technological, and that people will organize themselves to create and share translations for interesting web content, much as they already participate in collaborative systems like Wikipedia. If his essay is any sign of things to come (it has already been translated into 5 languages), this is a trend worth watching.
