I have just skimmed the word of OT and I know there is a common question that every such so called theory didn’t think about. That is the span of life. There are so many theories they think they are perfect (like Esperanto and Ido) but it is very easy to point out that they think the life of every body could be as long as they well. Without regard the life is limited no theory can be achieved.
Think about the following fact you may design a language by yourself.
Thinking process is like a process of speaking in mind. If in parallel speak, your language can send more information than other language, then your thinking speed would be faster than other language. I regard thinking speed or information sending and receiving speed is very important thing during a life. If decide how many information that you have enjoyed during a life gap. All the information technique is improving it. Yet if you speak a language that sending and receiving information very slow, this language could not survival long. The best example is the computer language. It has only two signals; we say that he can only utter two sounds 1 and 0. Just think about, the English has at least 400 different sounds. Suppose in the world, we just have 400 things to be expressed, then the English could be able to use each sounds to represent each things. While a two sound speaker have no such right. He has to use nine sounds as 011100101to express the same meaning of one sound that English uttered. That means to say, the two sounds’ speaker use nine times to do the same thing as English speaker spend one time. So the ‘fast’ and ‘slow’ is not the oral movement but the information’s transmitting. My principle is that to find a language that enable the people of the world to enjoy the maximum information during their individual life.
