whether you like it or not, nanotechnology will be a vital part of the future. think how nvidia created the new G80 chip with stream processors the could switch between two types based on the need. think of a CPU that can reconfigure itself on the fly to be what you need it. be it the best optimized architecture for editing videos, to running large databases.
nanotechnology will allow us to do this. i also believe that solar energy will be rejuvenated when it meets nanotechnology. think of a solar coating that is put on everything: buildings, clothes, even the sidewalk.
people may be afraid of nanotechnology cause they immediately think back to the Borg, but like it or not, nanotechnology is the future.
