My brother and I used to want to make a version of the internet back when we were dumb high school kids that would have everyone so dependent on it that they ABSOLUTLEY could not live without it - full immersion, IV's, etc.

The plan was to have a virus attack all the life support systems for the western world and leave the underdeveloped countries as the only people on the planet. Luckily, we weren't smart enough or motivated enough to make it happen...
