This firmly falls into the category of "evolving as a person" discussion GD and I had yesterday on another thread in that many people are unwilling or simply don't change their opinions/thought process in line with the ever changing World we live in, hence you end up with grumpy old "in my day" b*****ds that appear obsolete to the rest of us.
Will some of the youth of today fall into this category in 30/40 years time? Definitely! We've already seen examples of intolerance by younger generations in simply demanding various things banned as opposed to engaging in debate to why such things exist or happen and their reasoning why they shouldn't.
Simply put: Some people will continue to evolve alongside the World and some won't and remain stuck in the past.
