We only get to live ~70-80 years out of the technically infinite amount of time possibly, and who knows, time and space could break one day or something.
But that's an extremely insignificant amount of time to reside on Earth, and unless I'm destined to become famous and make a name for myself and my family, I could care less If I had to die tomorrow. I live day by day.
I hope when we die though we come out of this ultra-hightech machine and it turns out we were just playing a "game" of Earth Life and we then go back to living in our futuristic time in some far-away place that doesn't resemble Earth in any way and we're actually a race of extremely intelligent and sophisticated robots anmd instead of physical weapons we use some sort of mind-altering internal device that can destroy worlds from a medium we can't even comprehend.
And dubstep weapon cannons
