Futurologist Dr. Ian Pearson thinks that by the year 2050 we will be able to download our consciousness onto a computer and therefore become immortal. Don't forget to make a backup!
With this and Aubrey de Grey's theory, it is even more important to be healthy so that you can live long enough to live forever.

"The new PlayStation is 1 per cent as powerful as a human brain," he said. "It is into supercomputer status compared to 10 years ago. PlayStation 5 will probably be as powerful as the human brain."
He isn't talking about pure data here. Pearson believes that the human consciousness can be stored in digital format.

He also talks about the intelligent computers of the not-so-distant future:

Not everyone agrees, but it's my conclusion that it is possible to make a conscious computer with superhuman levels of intelligence before 2020."
'It would definitely have emotions - that's one of the primary reasons for doing it. If I'm on an airplane I want the computer to be more terrified of crashing than I am so it does everything to stay in the air until it's supposed to be on the ground.

Have you heard of the Singularity? From their website:

If technology can turn around and enhance intelligence, this closes the loop, creating a positive feedback effect. Smarter minds will be more effective at building still smarter minds.

It is pretty fascinating.
