In the early days of Free Republic, when I was surfing along on my 14.4kbps modem and people got pissy at you here if you so much as hot-linked an image (no, seriously, many modems at the time would choke while downloading a single JPEG), I was predicting that at some point in time, we would be able to store all the world's information on a chip the size of a fingernail and that all the movies and music in the world would be able to be streamed to you real time so you never even had to download anything anymore.
It sounded like science fiction at the time and that was only 25 years ago - late 1990s.
