I didn't even see my first terabyte until 1997 when I started a job to, among other things, manager a whopping FOUR terabytes of disc storage.
Now, my kids complain with sarcastic t-shirts:
Dad went to Disney World and all I got was a lousy terabyte!
Back when I was a kid we couldn't even afford binary; all we had were 0's. The rich neighbors down the street had 0's AND 1's. In an engineering lab in college we built an 8-bit storage latch out of transistors, barely above bearskins and flint knives, and clocked data in using pushbuttons. You got an A if your latch didn't catch fire.
I got a B-.
(It was a small fire, hardly worth using a fire extinguisher on. Srsly.)
My cat, who has more bytes in his flea collar than Carter has liver pills (look it up) got an A to give you a clue.
I don't know what I'm going to do with another terabyte. Did I mention that I already have three? Yeah, this will be number four, not to mention the multiple of gigabytes wandering around the household. Since my entire life fits into a flea collar I'm thinking about renting out the extra space.
I could become a byte slumlord. Sorta like the ring of that. At least I won't have to worry about plumbing.
