Each time, life experience can make the difference in a problem. Even if we try to demonstrate that young people know more things, a mature person can prove everytime that he’s methods are good, even if they are outdated. Even if the technology is in constant development, we can get the same result in a problem even if we use an old method, therefore life experience makes the difference. So I think the conflict between generations is why permanent contradictions between people of different ages continue.
