Not only energy concervation, but CREATION and restoration.
That is the pure magic part of the equasion.

It may turn out that sleeping is the MOST important part of it
because in the "sleeping domain" you might be getting the core
guidance to your entire activity in the "waking state".

Yes one can.
Boddhisattva went to China several hundred years ago
and that is how Zen started.
He sat in the room for 9 years, LITERALLY staring at the wall.
Thinking of NOTHING.
It wasn't even the issue of thinking.
It is pretty hard to grasp such a thing,
especially in the context of thought obscessed
word, but you can not simply dismiss the possibility.
What is the very essense of meditation?
Well, it is UTTER thoughtlessness.
What is awareness on the first place?
It is non evaluatory, simultaneous presence.
No thought. It is the very core of it.
That is what makes meditation a meditation.
Again, no thought.
This can not be denied.

This is invalid.
It is a byproduct of fear.

Which merely implies that CERTAIN focus and aspect is being ignored.
Refocusing occurs in a different domain.
Entity can not be denied the experience.
In "primitive" societies the brain functions in a quite
different ways outside of scope of your so called logic.
And yet there is a differen other kinds of "logic",
allowing and facilitating the life experiences in that
This can not be denied.
>That is the ingredient feature necessary for constant adaptability to
The essense of a human being is NOT "adaptability"
to ANY environment.
You CREATE that environement as you go.
The nature of human being is human experience
and environment is but a stage upon which this
play is taking place.
Yes, there is a particular appeal to a particular scope
and domain, but this is not the END of the story,
but a beginning.
> Neural networks must constantly form and change.
Where did you pull that one out from?
To facilitate what aspect of what?
Yes, the validity of neural structure can not be denied,
but your assumptions about the change is but a byproduct
of a particular inclinations, presently ruling your scope.
Furthermore, it is the same as stating "the rivers must
Ok, and then?
By that token, you must exist.
Ok, very fine argument.
What is the PURPOSE of that human expericence?
What is the purpose of intelligence?
Just to grow a pile of neurons, that are INEVITABLY

That looks like a bit of a limitation of the very
>Our ancestors had nothing to do at night, it was better not to make any

You are projecting your own fear of survival
because you are living in a MUCH more violent world
than you "ancestors".
You are operating on a mistaken model of a "predator/prey"
worldview, which is but a TOTAL delusion.
A bad dream.
A myth of the most destructive nature,
that brought you to the point of self anihilation.
As a result of that worldview, you are now hanging
on the hair think thread, just about the hell,
you have all invented and defined.

Not only conservation but refreshment, restoration,
enlargement, modification, adaptation, expansion
and things of that nature.
The focus definetely changes during the sleep,
but it is a well known "fact" that the brain does not
simply go into coma at night. It is HIGHLY active,
even though you can not quite decode that activity
as you simply deny yourself the very opportunity
to do so by constricting your own investigation,
choises and possibilities.
Some of the greatest discoveries of a mankind happened
Well, during sleep.
Historical record is evidence.
You go to sleep exhausted. You can not solve your problem.
It seems to be futile. You wasted half of your life on this
and you simply came to a dead end it seems.
Exhausted and even FRUSTRATED you let go and go to sleep.
And when you open your eyes in the morning...
Yes, that is how your discoveries are made.
During the day, you are largely grinding your own limitations.
During the night, you are free of those.
Well, you have your own private channel to your own superentity.
Hey, THAT is where the "discoveries" are made.
Can you allow this idea into your minds?

And yet, with that system, you can hardly create and
equivalent of an amoeba in terms of intelligence.
Yes, this is a bit stretching it,
but, neverthelesss, it points out the scope of your
You TOTALLY fail to grasp the grandior of your own being,
and spend all this time modelling a carbon copy of your
intelligence, failing to even consider the possibility
that there is simply no need to create a copy of you
as YOU are there to experience the life and not a machine,
you are trying to create.
You can try to make your car "intelligent".
You can try to make your weapons "intelligent",
but still, for some strange reason, those
EXTREMELY "intelligent" weapons hit the Chinese
embasy in Belgrade.
So, the whole thing is just a scam on the first place?
There is simply not even a HINT of intelligence in
those "intelligent" bombs of yours. Not even a hint.
You merely carbon copied the MOST primitive aspects
of a functioning intelligence, created for the biological
life in order to EXPERIENCE the phisical domain.
You took the single dimension of that intelligent,
and not even that much, you took a single point,
isolated it from the whole, and used it to do what?
Well, to destroy.
This is nothing much to brag about.
>ANN systems resembling neural networks of our brain would receive
>constant inputs as well in the form of internal thought processes,
Internal thought process is a mechanism for the biological
intelligence to EXPERIENCE the physical domain and learn
the nature of its own entity and life force as such.
It is simply inapplicable to a machine, no matter what kind
of software you are going to put in.
No matter how hard you model your most intricate mechanisms,
it can not possibly function as intelligence.
You simply removed the CORE of it.
All you have is a plastic lable on a bottle of coca cola.

This is trivial.

This is merely the issues of efficiency
and not the issue of principle.
You are merely optimizing the performance
or conserving energy, whatever pleases you more.
It does not change ANYTHING at the core of the issues.
