Robot

The humanoid robot is for the human emotion, not the best work or combat machine. The machines dispatched on the front line should be omnidirectional, and the joints should be rotated at all angles.  The machines created by the creatures with heads and tails seem not easy to get out of heads and tails: cars, ships, aircrafts............

Metaverse @ Cloud

Cloud: the union of storages, computing and communication resources of the whole world. 

Metaverse: the union of virtual realities (synchronizing or no synchronizing with realities) of the whole world.

The Real Cloud

The real Cloud should let the application softwares do not need to care about what type and how many hardwares to execute. 

In addition to the Cloud hardware scalability, the Cloud software must be scalable too to be easy to move and dynamically allocate during runtime. 

What the goal the Real Cloud system really wants is not only a traditional client-server architecture even if the services could be moved and dynamically allocated during runtime on different servers, but also a peer to peer architecture among big and small hardwares.
