Exactly this. We think we are tech savvy because we are better than them at our tech. That tech was plumbing for your dad, and it’s something 90s-00s for me. My kids do stuff better than me that I don’t even consider tech but it probably is.

That’s how you become an old person that know nothing about tech - you keep being good at tech and don’t consider the stuff you aren’t good as to be tech. Eventually that other tech is all there is and you are now your dad.
