The first stone etchings or inlays required about one square inch per character. Today, silicon computer chips are approaching the packing density of one billion transistors by the year 2005. As quantum physics is tapped for digitizing data, existing storage of media will probably increase by as much as one trillion fold. Packing density is one dimension of responding to your question. 8-track tapes, cassette tapes, floppy disks, disk drives with constantly changing character reading devices which are about to take a huge quantum leap.
Progress is the name of the game.
ET Space vacations, as such, already are available. For example, if you have enough money, you can get a ride on a MIG 25 Soviet aircraft to the edge of space. There are numerous other examples. Needless to say, it's all a matter of perspective and how far you want to go out from planet earth. ET Education, there is no doubt in my mind, is the most important single investment an individual will ever make.
