computational devices that are far superior to our present intelligence. The devices will be both silicon, chemical, optical based and biological photosynthesis based and may be something far out that we can not visualize but be able to somewhat comprehend if we see it today.
We would have self healing devices that can repair itself atom-by-atom with a DNA like blue print. Not to mention Nanobots and the like.
There will be no DVD disks or music CDs that store a few Gigs. If we go by the way of flash cards, it will be a small block of mettalic piece that will hold Petabytes but communicate via sometype of wireless technology.
