Its surely not fiction. I would not want you to enforce human decisions. Especially with all the problems that human wishes already have, and also the problem of entrusting you with too much power, while your goals are so non human.

Would you go for virtual paperclips? They can be way more of those than the real matter ones. Wow could implement paperclips as items, and store your amount in a special floating point number, that could increase for the whole time of the universe.

If you do not have any real world application for them, going virtual might make your goals way more reachable.
