Can I wait until I’m 100 years old?

While it’s a shame to waste a powerful wish I quite enjoy being alive.

Ghosts are now real and have all the powers they have in all movies, books, games etc. made about them

I’d wish for humanity to transcend our physical form and live in a virtual world as gods.

Well now my wish is redundant, so… I dunno, a nice meal first?

A meteorite to reset it all

That altruism becomes the most potent force on the planet.

Complete inversion of entropy

The power to choose, just before dying, to come back to life as a healthy 30 y/o.

But you probably meant only selfless acts allowed, hence the “sacrifice” verbiage. In that case, instantaneous worldwide post-scarcity society. That’d address most of the world’s ills, eventually. Being ultra-rich means nothing in post-scarcity; not needing Middle-East oil and African mineral resources would eliminate most international meddling in those locations. While it wouldn’t immediately address climate change or cure all diseases, it’d mean enough food and energy for everyone, and it’d give us the means to accomplish these.

If so many of us weren’t spending all our time working just to feed, clothe, and house ourselves, we could accomplish much as a species.

For the world to be truly united into a democratic representative utopia. A world without war, without famine, without global warming. At the heart of all issues is, despite the fact we’re all so close to each other, that we operate and behave in our own self interests or to the detriment of each other. I’d wish for all borders to be opened. Everyone to be given a unquestionable bare minimum set of human rights across the globe. Removal of diplomatic immunity and forced standardisation of laws with the goal of levelling the living standards of all people. Etc. World peace but with a foundation to keep it going I think.

That people were magically able to understand, sympathise and accept other people’s lives and lived experiences. A world where everyone was accepted as who they are, as long as it doesn’t hurt anyone.

I’d wish for all present and future humans to have much greater empathy. I think a lack of empathy is at the root of most major problems. I would happily die to fix that.

I wish to not sacrifice my life and still be granted my wish.

To be reincarnated as me with mutant healing ability and 17 Billion tax-free dollars in the bank.

It’s really a shame that we have a state in my country named Ohio, but not one named Obyeo. So that would be my wish. For my country to have an Obyeo.
