Some people once thought a Dr. Who original episode, once shown, was straight up garbage. Ask a widower if he'd like copies of all old emails, text messages, etc from his spouse. Straight up garbage to you and me, but to him, maybe not. I think we are producing data that is of interest to N people (N >0) at a rate that outpaces our ability to store them. But this does not keep me lying awake at night. So long, as you point out, I have an archival procedure for all the junk I care about.
