If I can use myself as an example of the "older generation", our household isn't one where the parents are totally mystified by the computer or modern electronic doo-dads.
I have had a strong interest in technology and technical progress for many years and can show my kids a thing or two about what makes motor vehicles work. (Fact is, they know zip about cars). I also repair most of the appliances around the house when they cark it. I do rely on my son (23) for advice re access to on-line programs which he becomes aware of because he is a greater user of the pc than me, but I know more about things like Excel and Word, which were bread and butter to me in my former employment.
Ultimately, he will increase his knowledge of computer programs whereas I will not want to keep up to date as I age. In ten years, he will probably be showing me how to turn his brand new, latest tech computer on because they will have deleted the power key and I won't have a clue what to look for.
