Anecdote time. Years ago, I used to use yt-dlp to archive videos I'd like to keep forever. I had a few terabytes of videos, some of which didn't even exist on YouTube anymore. Then, one day, my hard drive suddenly died. I lost everything. Now I don't archive stuff anymore, and my life goes on just the same. Sometimes, I do miss something I used to hoard, but I just nurture the nostalgia and rely on my memory alone.
