To be sure, I am probably more like a casual data hoarder—only hoarding files I will revisit (I have a TV app I wrote that plays these videos on a schedule—a lot like these "HN TV" sites we've been seeing vibe-coded lately).
But it does take a non-zero amount of time to copy/paste a URL and then move the files to external storage when my laptop gets heavy with data.
And while it does feel a bit like a mental sickness (really, sickness?) I have other behaviors like spending too much time on YouTube in general that unfortunately would persist whether I was hoarding or not.
I do try to walk away from the browser more these days—limit it to a few hours in the morning and then when I am eating lunch or whatever during the day.
