Interesting perspective but with all of that experience are you not able to communicate with them in their way? This seems a bit like missing the forest for the trees, people are no less thoughtful or complex based on where they've lived or what they've done. The experiences you are learning from came at a cost of the experiences like those of your parents, those experiences shape their communication. There is absolutely a multitude of wisdom only age and their experiences can create but you have to learn to bridge the gap.
Not all experiences are created equal. They have some type of experience in droves, but mine is much... wider and more varied for the lack of better words. Their days looked one like another, very little variety. Same people, same situations whole lives. It really limits one's experience, and living 5000 years in such environment doesn't add up that much.
One example is that psychology - they are just not wired to look at complexities of other people's emotions, origins, mental issues and so on. People are good or bad, weird is a third state for them and thats it. They are trivial to manipulate via emotions, just like their whole generation is.
I mean I talk to them regularly, but its rather shallow talk. Anytime I go deeper ie about my deeper experiences in some remote place and culture, their face goes blank, they don't have much to add. They look at the photos and love those but that's a very tiny part of whole story. I learned over decades what topics work and which are for other people.
Its all fine, apologies if I sounded worse than things are. Parents are just parents, for adults they are not meant to be the closest people in the world, that's rather an indication of some social failure to find and integrate with peers down the line.
