Think about the English language: it is very simple, consisting of only 26 letters. And to my understanding, European languages have finite alphabets as well. Now compare that to Chinese, which has no alphabet but instead thousands of characters - Mao's simplified Chinese does little to make things better. Could a simpler language lead to a greater rate of invention? I mean, the time spent detailing with the nitty gritty details of the language could be spent on more high-level ideas, like mathematics. As a side note, what area of linguistics focuses on rewriting existing languages?
