# Immortality

Is immortality possible?

Is human immortality possible ?

Before to try to answer this question we need to define what is life.

If we think to us as biological entity this become a biologic question , if we think to us as physical matter this become a physic question.

I think the human being is inside the mind and the mind is not a physic object .

Anyway I think everything is ultimately a program so I try to give an answer by defining a person as a program.

I am not saying that we can define a human as the program implemented by the brain because we know the brain change ; the brain change its matter and ( most important ) change its connections , change its program so if we want do define a person to be the same after some hours when his brain change we can not bound the program by the brain but by the program that change the brain .

The main question is : what happen if we run a program for an unlimited amount of time? There are 2 possibilities

1) enter in a loop (infinite loop) where it go to reuse previous state ( class 1 programs )

2) use always new states so eats every information resource

So in the first case the program die because make always the same things. He remember the same things he can not remember about different loop . It is not like in a movie where the protagonist everyday remember that the previous day is equal to the new day . It is not possible to remember that , to recognize that because it need more memory, it need more states but the program has not more new states so it is really a death.

In the second case the program become U because the difference between the program and U ( where U is the computational implementation of the unification of the physical law , the universe ) become infinitely less significant .

In this scenario I suppose the universe is discrete and the conclusion is that immortality ( as its extreme definition of an infinite life ) of programs is not possible .

# Artificial intelligence evolution

These are the possible scenario of Artificial intelligence compared to human intelligence.

1) The brain is a simple full parrallel machine that simulate a sequential process and if we will be not able to construct quantum computer (without an exponential effort to increase the number of qubits) the consequence will be an artificial intelligence thousand of time more powerfull than human.

2) The brain is a simple full parrallel machine that simulate a single process and if we will be able to construct quantum computer (without an exponential effort to increase the number of qubits) the consequence will be an artificial intelligence exponentially more powerfull than human.

3) The brain is a quantum machine  and  we will be not able to construct quantum computer the exponential grow of computer power will compensate the exponental power of brain so in linear time the Artificial intelligent will become more powerfull than human brain.

4) Into the brain there is something so powerfull we don’t know and we never seen . Ok in this case the brain will remain the number one.

# The Brain and the Mind

To well understand the difference between brain and mind I have this simple experiment.
