The first harddisk I had on a PC clone was 20MB, which was a lot then but it failed before I could fill it up. A couple of years later I got a machine with 40MB disk, but that one filled up so quickly that the machine was useless after a couple of months. Now I have a computer with storage nearly 2TB, I expect it to fill up quickly. And a million times (literally) more memory than the first IBM PC. Way way more than any of the predictions from a decade or two back, including those from such as Neil Stephenson and William Gibson
