Almost everyone heard about Ray Kurzweil.
He has an important position in Google company, and he has a brilliant mind, inventing
a lot of very useful things.
He says in some interviews that before 2040 - 2045 immortality will be achieved,
one of the interviews is here:

But many people found a problem with a definition of immortality of the brain
as simply downloading the brain information onto a hard disk.
It sounds just like downloading photos you made in a holiday, onto a hard disk,
from the digital camera.
This doesn´t mean that the photos are you, or that the photos have conciousness.
Recreating a hologram from some DNA cells from his father, will not really make his father
alive again, but rather some kind of copy of his image, like an improved 3d moving photo of
his father.
Downloading memories on a storage is not immortality.
It is just a better storage of memories.
Ray Kurzweil is already 67 years old. He should focus on what is the most important:
to find all the ways to rejuvenate his mind and body, so that his risk of dying is minimal,
because he is already quite old.
I find it strange that he does not focus all his resources on this most important aim.
Maybe we should remind him?
