The 35-year-old Russian is the founder of the 2045 Initiative, which is an organisation working on making immortality a reality by scientists creating a feasible program which maps the brain.
It then transfers the mind onto a computer, which is put on a robot body or as a hologram.
Mr Itskov has been subject to a BBC documentary titled The Immortalist, in which he said: "Within the next 30 years, I am going to make sure that we can all live forever.
“I'm 100 per cent confident it will happen. Otherwise I wouldn't have started it.”
The 2045 Initiative hopes to have functioning 'avatars’ by 2020 where a human will be able to control a robot via their brain.
Five years later, the team will create another form of avatar which will be able to host a human brain that will have been transferred after the person has died.
By 2035, the network of scientists aim to have an avatar with an artificial brain which can possess a human personality.
The team will have completed the trans-human beings by 2045 when they hope to have a hologram-like avatar.
Some scientists have questioned whether transferring a human brain to a computer is a realistic goal, but this hasn’t deterred Itskov from his ambition which he hopes to make available to everyone eventually.
He told the Sunday Times: "Eternity is when unlimited creative possibilities are present in life, when there are no limits or boundaries for development, learning, culture and creativity.
"I want all of this to be available to every person, including myself.
“And to a lesser degree I am motivated by the fear of death and the wish to postpone [that] moment."
