A building is similar to a human body

A lot of what we engineer and design is in the image of nature.
For instance, a building is similar to the human body in design.
Security = Immune system
Lift/Stairs = Circulatory system
Plumbing = Water system/Excretory system
Electrical system = Nervous system
Building Beams and Columns = Skeletal system
Bricks, Cement, Paint = Muscular/Skin system
Fans/ACs = Cooling system/Sweat glands.
Natural Gas system = Digestive(fire) system.

We design like nature because,
Ultimately we want all designs to serve us,
i.e. to enhance our well-being and riches.
So technology will come closer and closer to our bio-machine,
Finally integrate itself into it, taking us to trans-humanism.
Eventually it will remove time-space limitations fully.
We would form a singular global net,
With instant communication/experience possibilities.
