As a 30 year old adult who has both Ne and Si, I see the value in both. Innovation while totally rejecting what has come before is dangerous and possibly stupid, but tradition without questioning those traditions or creating anything new also seems self-defeating and ignorant to me. There has to be a balance of both.
I actually get annoyed with people who want to completely reject the way everything was before, because I feel they're rejecting important factual information and things that were of value and quality of the past. If we do not learn from our past, we are doomed to repeat it.
Plus, houses and buildings built in the 19th century have a level of craftsmanship that is often entirely neglected today, and I think people who have no sense of preservation are kind of retarded. These people may also reject the importance of Earth and nature.
On the other hand, tradition for traditions sake while ignoring new information, facts, or ideas is equally retarded. See: extremely conservative fundamentalist Christian Republicans.
