It’s the Bilboa Bagging effect. It’s yearning for a time that no longer exists. Both because you’ve grown and changed and the world has grown and changed. You’ll never capture that again. And maybe it wasn’t even the way you are remembering it in the first place.

At best you could attempt to replicate it with all of the new tech, people, and social norms but there isn’t “reset the clock 20 years”. Thats a lazy copout and hardly a solution. Why not just say “everyone just needs to be better”?
