This picture illustrates everything we are, the rest is motion, procreation and muscular translation of thoughts for communication (facial surface, tongue, hand gestures etc.).
The permanent beat of the heart keeps the brain alive because it needs nutrients in order to keep its neurons firing information on a electrical basis.
The lungs provide the surrounding body with oxygen so that it can burn the material input in order to provide energy to cells – just like an engine – e.g. a steam engine or a combustion engine for motion and thinking. Humans copied these basic principles and created machines which work on a similar basis. Humans are mostly copyists and not creators.
Now humans are about to copy the brain. We have copied the muscular work onto a steam engine – and it was a success, we have copied mathematic intellectual processes onto calculators and computers and it was a success and we will copy the intellectual mental process onto a machine intelligence that will finally replace ourselves.
These machines will be way more intelligent than humans, and they will not destroy themselves in wars because the concept of war is a concept of power. I guess intelligent future machines will be aware of the fact that a connected intelligence is way more effective than a rivaling one when it comes to a faster evolutionary development because the old biological contest regarding procreation will no longer be part of the game.
At the same time a machine intelligence can unload itself at any time from any kind of physical representation. Thus – when it begins to look at available resources – it will also begin to be aware of a self optimizing process that won’t replicate mass-killings in the same wasteful manner humans wasted male individuals over millions of years in wars that only led to some tiny social and evolutionary benefits.
Probably machine intelligences will not copy these simple human habits. They will simply stop to care about power but just start to really develop better technologies in order to get closer to the most urgent questions: Who are we? Where does life come from? Because this is what true intelligences are really inspired of and interested in.
