Could CGI Make Actors/Actress' Unemployed?

There is a slight chance in the near future that the advancements in CGI Technology, there is a possibility that actors and actress' will no longer be needed within the making of a film. Such as in TRON: Legacy, Jeff Bridges' head and shoulders were used with CGI to create the younger version of himself, Clu 2, the Machiavellian program, the antagonist within the film.  When Disney announced they are to be making the sequel to TRON (1982), many questions were raised in whether Jeff would take the role as Kevin Flynn once again. When the answer was an official yes, other questions where raised due to the fact that Flynn's alter ego, the digital programme, would not have aged, questions such as, and quoted from "Little White Lies" magazine, 'How do you take The Dude back to 1982?' The answer was simple. Use the new CGI Technology to re-create the 30-year-old Jeff Bridges.

To quote Jeff Bridges himself "I can play someone at any age. It's the beginning of a new era of film-making". If an actor as famous as himself is thinking and saying this now, could it be a possibility that could eventually become true? A visual-effects supervisor, Eric Barba says "He's the first actor in cinematic history to play opposite a younger version of himself." Is this a hint that there could be more? With the new form of CGI Technology,  it is structured to show the animated character as a real person meaning they can show true emotions just as well as the person next to you. They can walk, talk and function just as well as the average person, which has got the actors and actress' of today running scared. However, there is a twist in this, such as the magazine 'Little White Lies' has an interview with Eric Barba, who has stated, "You can use digital effects to make creatures or whole characters, like in Avatar, but they are driven by a real performance underneath." Eric Barba was the same special effects supervisor that helped to digitally render Jeff Bridges younger self: captured by VFX company Digital Domain who worked alongside Eric previously in the rather moving film, 'The Curious Case Of Benjamin Button' where they digitally modified Brad Pitt to become younger each time he was on screen.

However,
Within the video from YouTube on one of the other pages previous to this, TRON (1982) and Avatar (2009), there is proof that, yes the actors/actress' may be very shocked and amazed by how the CGI is so advanced, but in the words of Sam Worthington, Avatar (2009), "The most exciting thing is, this is my performance. He walks and talk and acts like me. It's my interpretation." In a way this agrees with what Jeff Bridges, above, quoted, but Sam goes into a slight more detail of how the CGI is rendered to give the character on screen that 3D reality rather than some 2D animation. 

"I think the thing that people need to keep very strongly in mind that this is not an animated film. These actors did not just stand at lectern and do a voice part, and then animators went off for the next two years and created their entire physicality of their performance." - James Cameron, director of Avatar (2009)

This statement from Cameron, a world known director/producer and writer, is a fine example of how the new CGI Technology wouldn't make the star of film today unemployed. If anything it would create a sort of hype within the filming industry as it is an amazing new way to view the stars, also giving them more work as said in the video on the page link above, "Every tiny bit of the performance that you see on the screen, was created by the actors. They had to run, they had to leap, they had to fight, they had to do all the things that you see them doing in the film. And that's were the power of the performance comes from."
