I now realized that currently, a computer language is going to be similar to a human language. It is good idea for people to use it easily. However, I think, in order to be much easier for each human, the computer language should be adapted to each user. Remind that any previous computer language are not changed automatically as a function of the user style. Some object oriented languages can be changed their keyword functions by user programing but not be changed automatically based on interaction with a user.My language style, I believe, is quite different from my friend's one. Hence, I can say that there must be something to be learned from a user but not only something which a user must study.
