I already said this in some post, but the world i envision if i were have this power would be a world where everything you work hard for can guarentee you 100% sucess. Creating an utophia where everything would be there for you by not doing something would just be boring
My depression came from the fact that no matter how hard you work to achieve thing. There will be always someone who's better than you.
Maybe just to add more, i hope for the world where assisted suicide is a normal thing and not a taboo, so people who had enough with life can just log off without being ashamed or have to go through hard time to find a resource
But hey, this's just my made up dream reality, in the end lot of people gonna suffer for some reason, and there's someone who's better that you at everything
