But if all memory are stored perfectly where are they?? LoL and a popular saying it's our memories that make who we are... So who we are are just a collection of memory stored on top of basic raw instincts (pain, danger etc) layer by layer...
This is why I'm a firm believer of a combined linked super conscious (almost like a hive instinct but not completely external in nature)... And we connect to it when we're sleeping to dump information all of us... This is why we can't survive without dreaming and sleeping...
I think something else, but something related. This seems like a good time to bring it up:
Intelligence is the result of structured communication. Intelligence can be formed in hierarchies. One example of this is in ants. Ants have a central nervous system - the individual can do some basic, instinctive stuff, but not a lot. Get a lot of ants together, though, and they all communicate through hormones. They end up designing intricate tunnel systems which are comparable in complexity to man made designs. The intelligence is thought not to come from any individual ant, but from the ants communicating with one another.
But the individual ants are likely unaware of the intelligence that they are a part of.
Then look at humans: We have a central nervous system including the brain. The brain contains neurones which network in many confusing topologies, the exploration of which is a goal of neuroscience. The key idea behind neurones is that their usefulness does not stem at the individual level, but in the way that neurones synapse - where they join together - how they communicate is what is important. The individual neurones aren't intelligent. A functional subset of the brain would not normally be considered intelligent. However, taken as a whole, the human brain produces what we experience as self awareness, consciousness, intelligence. Whatever you want to call it.
What people would intuitively believe is that an individual human is at the top of his own intelligence hierarchy.
However, people communicate with other people, frequently in a structured way. People form social networks which can form weird topologies. Is it possible that the interactions between humans creates an intelligence in its own right that we're simply not aware of because we cannot see it? Does it create? Does it use us? Do we use it? What does globalisation imply about it - like for instance, were there perhaps many disjoint intelligences until global communication was formed? What if, given that it is a network made up of billions of beings that experience emotions, the 'super intelligence' experiences emotions of its own that we could never comprehend?
If we are the ants, what is our colony doing?
tl;dr: We might be part of a greater intelligence already - while wide awake, not while asleep.
