I find hard to believe every language in the planet can be successfully expressed using some sort of alphabetic system, except for Japanese/Chinese (and local variants)
They could be written alphabetically, of course. The question is just what you lose, given that the characters are a massive part of Chinese and Japanese culture.
Chinese has evolved alongside its writing system for about 3000 years, and switching over to pinyin (the standard Latin transliteration) would be a complete revolution in Chinese culture.
I was responding to the assertion that writing Chinese using an alphabet would render the text incomprehensible, not arguing that China or Japan should switch over.
