The people of today are more educated than the people of the past; we can't move forward by staying stuck in the past.
Old rules and forms of government don't work for today's cultures and societies. Old ways of thinking are a detriment to the freedoms that are enjoyed by women and minorities today. Old tech is outdated and obsolete.
The only way to move forward is to create new and innovative ideas, and these can only be found in the here and now.
