I'm not sure why you're getting so defensive; I indeed don't speak Chinese, hence why I'm asking a question.
A claim like "Chinese as a language is less technical and specific than English and slows progress" seems pretty grand; and if Chinese people failed to launch satellites in orbit or do brain surgery you could point to that; but they don't seem to be held back by their language when it comes to making specific, technical achievements, so I'm curious to hear actual, concrete details or examples about what makes Chinese a "less technical and specific" language.
It sounds like your answer is "it simply just is, because it's a courtly language" - which is not a very satisfying answer, intellectually speaking.
