It would be a loss IMO if future generations never knew that we even engaged in doomscrolling (or to what extent). Of all things you’d want future generations to learn from, maladaptive behavior that’s so widespread as to be hardly noticed in daily life seem high on the list.
Caveat that doomscrolling specifically maybe isn’t a great example given that we are collecting a ton of data about it, we’re mostly just ignoring it.
