Atom-size microchips are coming.

Theoretically, researchers can create transistors using three carbon or metal atoms. The base, collector, and emitter would be atom-size structures. 

The atoms that spin are controlled and can input electricity to that system. Two, or maybe three-atom-size structures can form switches and routers. 

That thing can make ultra-small microchips possible. Atom-size routers and switches are coming to microchip technology. The system's base is in a system. That controls the atom's spin. And that can unlock new and very fast processor technology. Miniature, nano-size microchips are tools that make many things possible. 

Nano-size microchips can control nanomachines. The problem with nanomachines is their small size. The outside remote controller can control those tools. However, they cannot operate in electromagnetic fields which limits their ability to operate for medical purposes. The small microchips allow those systems to operate as well as in versatile missions. 

They can drive as complicated code as larger computers. The new microchip technology opens new routes for medical and military applications. 

There are two versions of independently operating machines. First uses outside computers to control it. The system uses remote controllers that are connected to outside computers. The independent operating machine that uses an internal command unit is independent of remote controllers and data transmission channels. That makes it hard to affect them from the outside. 

And that is one of the wildest things that we can imagine. The futuristic liquid robots that can change their shape are groups of nanomachines. Those systems seem solid structures. But they are a large group of small silicone nano-robots. 

Nano-size microchips are also tools that can operate very highly intelligent robots. The system that fits in the human-size robots can have far more calculation units than in the highest-power supercomputers. And that makes them drive very complicated codes and algorithms. Those robots can be far more intelligent than even humans.
