Why robot can't be just a hand?

I just remembered one "Donald Duck"-cartoon, where the "bad guy" had an assistant, what was actually a robot. That thing was impossible at that time but in fact, this hand, what might seem like the iron glove, what knights used with their body armor can operate with the small size-drone helicopter. In the hand might installed the hydraulic piston, what makes possible to reach the had to the target.

Hand-shaped small size flying manipulator might give assistance to workers in many places. If the system wanted to be work in some places, there is no room for use that drone helicopter, would that small drone just release the hand what would travel in those tight places like some spider. In fact, this kind of system might be useful also in space programs.

Those hands could work independently as the miniaturized spacecraft, what are equipped with small rocket engines, and the wrist may have the electric motor to rotate the hand in the right direction. These systems can use to fix the problems in the outer layer of the spacecraft, and in the orbital trajectory would be no problem with the gravity or air, what makes difficult to operate this kind of things in the surface of Earth.

But in fact, if we could create the anti gravity device, we could make possible to create the robot, what is like hovering hand. If we would have magnets, what have extremely powerful magnets, those systems can create the structure, what looks like a slot, and it can hover this thing between the magnets. And the moving magnets inside that thing can help to rotate and move it. But in fact, we could use similar systems, what are created for some ASAT-systems. The system might be modified gas pistol, what is used in space flights, and in this time it would only installed in the glove-looking robot. In this case, the hand would fly on the air by using tiny rocket motors. The operator would use VR-systems and cameras, what is installed in that hand.

The AI-based PCs will replace current PCs quite soon. A Lenovo director says.

The AI-based PCs will replace current PCs quite soon. A Lenovo director says. Lenovo plans to replace current PCs by using new AI-based systems. The AI-based PC is the tool that makes computing more powerful, more effective, and safer than ever before. The Kernel-based AI that guards computers and identifies the users are tools that are required at this time of modern computing. The problem with this type of advantage is that if those AI-based system's servers are in China, makes the PC an ultimate control tool. Another thing is that the host who controls servers can use data collected from the users to create military AI applications. Computer games help to create AI that can respond to all types of actions. And AI also can create things like hypersonic lifting bodies and command systems for military tools. Also, AI can create new types of dual-use systems that control drone swarms in marketing situations for making dragon images in the skies. But the same systems can contro

Quantum computers and ultra-fast photonic microchips can danger even the most secure communication.

"Quantum computers could pose a major security risk to current communication systems in 12-15 years with their exponentially greater speed and code-breaking ability. (ScitechDaily, Today’s Most-Secure Communications Threatened by Future Quantum Computers) Quantum computers can break entire binary cryptography. And that makes all communication unsecured. That is one of the greatest threats in quantum computing. And this brings the arms race to the quantum age. The quantum computer can create codes that any binary computer can break. But the quantum computer can also break old-fashioned codes. And that makes it an ultimate weapon and sabotage tool. Quantum computers can change the measurements of the ammunition in factories by changing the system calibration. Or it can delete databases from the opponent's computer systems. This thing can delete all SIM cards from mobile telephones. In peacetime, the hackers that operate using quantum systems can steal the names of the counter-

The new 3D printers are coin-size systems.

"The tiny device could enable a user to rapidly create customized, low-cost objects on the go, like a fastener to repair a wobbly bicycle wheel or a component for a critical medical operation. Credit: Sampson Wilcox, RLE" (Scitech, Tiny Titan: MIT’s Revolutionary Coin-Sized 3D Printer Fits in Your Pocket) Researchers created a 3D printer that is coin-size. That kind of printer can create things like microchips. But it's possible. Those tiny 3D printers can also work in extremely large-size projects. In simplest models, the 3D printers are positioned on tracks. The 3D printer itself is the tool, that can be part of the modular production systems. There are visions of high-temperature metal printers installed on the gantry cranes. That makes those crane printers that can make even ship-size things. The crane that the printer controls can move back and forth and the printer can move horizontally. This kind of thing can turn the crane into a high-temperature 3D printer, that
