I have family photos starting in 2001, scanned/captured photos and video going back 50 years, music, and backups of all my Xbox DVDs (WTF is the original Xbox even called today?). But that’s a few terrabytes. It can all fit on a few USB sticks. (Which I do as a third level backup.)
The real space killers are the TV shows and movies that I will watch at most once every 20 years. I could delete almost all of it. But I don’t. Instead I keep looking for bigger storage options.







You can approach the speed of light but you cannot reach it. Your equations are missing the relativistic corrections.
