Russian Billionaire wants to make humans Immortal by 2045

Helped by the latest progress in Technology a Russian billionaire, Dmitry Itskov, founded in 2011 "movement 2045"

Many books, movies, mythology have played with the idea of Immortality. The idea of immortality can be traced through history since the beginning of civilization. Presently immortality may soon become a grasping reality.

The 2045 movement aims to make humans immortal by transferring their personalities into android body, something like the movies Avatar or Transcendence.

Their Concept involves 4 Steps:

Avatar A aims to give humans the ability to control Robots with the help of our brain(by thoughts). This Technology has already been achieved. See:

Avatar B, a more complex and evolved concept is to transplant the Brain into a robotic body. This is actually a transfer of consciousness, a physical one. This idea is ancient and was stated first by Pitagora and popularized by Plato:

Avatar C, this is the next level. It is resembling the Avatar B, but this one really takes us to the movie AVATAR and Transcendence. This only upload a humans thoughts, memories, personality..consciousness into a ROBOT. MINDBLOWN.

Latest Evolution would be Avatar D. Which is actually a hologram-like Person..pretty meehh. A sentient hologram. Not just a memory like Superman's parents.

Ups and Downs of Immortality.

First things which comes to mind is ... how...or what kind of pleasures would such kind of thing have. Would the android body resemble the ones from WestWorld?! Could they eat, have sex and so on?!
Without the fear of death how will the society change? We will have more crimes, wars and so on? Will people still marry?
A positive aspect is that with a looooot more time to spend, world's greatest mind could continue to develop and implicitly we as a race would continue to advance.

Wouldn't have been nice to have an immortal Einstein? or Turing? or Da Vinci?

What are your thoughts on this?
