I actually do believe this is a reality in our lifetimes
It almost certainly won't, but realistically speaking, even if it does happen, YOU will still be dead, even if a copy of your brain has been archived in a server somewhere and is continuing to operate with the delusion of still being "you".
Unless we go the more mundane route and find a way to preserve the human brain itself indefinitely in a jar full of nutrient fluids, then hook a USB cable directly into the severed stump of your spine and spoof nervous system signals in to give you the illusion of still having a body. But that level of technology is almost certainly farther off than just being able to make a fully digital copy of a brain.
Do you believe in the tech singularity and, if so, do you believe it is more than 50 years away?
