Doesnt matter what they say and think about your problems, if the problems they experienced through their lives have no overlap with the problems you experience

Doesnt matter what they say and think about your problems, if the problems they experienced through their lives have no overlap with the problems you experience. Your grandkids will grow up in a completely different reality to yours due to how fast the world is changing. When they do come to you with their issues, unless you have life experience solving similar issues, how does it matter what you think or say about their issues?
