People fear death more than anything, fearing the possibility of an afterlife or ceasing to exist entirely. If you discovered a way, to however, upload your mind into a computer's database, would you do it? There, you would technically exist forever and be immortal in that space you live in. The only way you would cease to exist is if your database was deleted, or the computer(s) your mind is attached to is destroyed. The cost of this however, is you are forever alone, and trapped in a space of blank darkness and numbers, and your only source of communication are the people who turn on the computer. There is otherwise nothing to do in this existence, and you can only quietly contemplate your memories of the life before.
