If you copy your brain digitally and let that run while you yourself die, there's no benefit to yourself. You still die. You don't get to experience longevity. What would live on is a copy of yourself that believes itself to be the same person as you were. Your yourself would have no continuity of thought.
What would be needed is some way of merging yourself with a digital replica of your brain while you're still alive. I can't even begin to imagine what that would be like.
