Obviously first wish would be not to die, pass on, or something like that. But just ruins the fun now doesn’t it? My dying wish would be the well-being of my family. That’s the most realistic one.
Unrealistic wish?
Fly a rocket tank into space and destroy the space-droid armada.
My wish would be, if I really were to make an exit from life, that I exit in style. The lasts moments of my life is what everyone I know in person very well, and consider good friends, will remember about me, and what will be my last memory. Why not make those last moments as amazing as possible, afterall, life is to be enjoyed, and I think that counts even when you haven’t got much time left.
I want to be reincarnated in an AI named Epsilon, that would have all of my memories. I would serve as a military Artificial Intelligence used to help soldiers use their equipment in battle.
To be reborn as something cool, like a lammergeier (the coolest vulture who never has to work hard for food), a mantis shrimp (the best animal), a falcon, or a housecoat with a loving owner.
Or for some reason, a sentient tree that would live a long time.
