The following concepts, although not currently implemented, are considered fair predictions for the near future:

• nanotechnology (a term coined by Eric Drexler in his book Engines of Creation) is the technological control over the structure of matter at the atomic level. Drexler predicts virus-sized computers/robots. The "nanites" would be, essentially, very complex molecules, assembled one atom at a time. Each would have some specific purpose. Microminiaturization will have many advantages. Computers can gain far larger caches of RAM and ROM. But the nanites can also be used to engineer people themselves. For example, microscopic robots can be inserted into the human body to remove disease and to expand the power of the human mind. Nantes will have the ability to self-replicate, building new nanites by utilizing organic materials. The big hope is that they can eventually assemble larger objects, like living human organs
• human level software/hardware involves making cybernetic equipment on the same level of complexity as the human brain. One of the implications is that the human consciousness itself could be uploaded into a mainframe Posed are some interesting possibilities, notably that the individual consciousness could attain a sort of immortality (at least as long as the system was operational!)
• A utility fog is, essentially, a cloud of nanites that can act in conjunction with each other. The nanites would have to be suspended in some sort of zero-G environment, Computer instructions to the nanites allow them to reconfigure their shape and conduct actions. So, for example, an astronaut in a space ship chamber containing a utility fog could order the fog to form any sort of instrument the astronaut might currently need, have the fog flow over a breach in the hull and seal it, or even move radioactive items about safely.
