Everyone religious wakes up tomorrow realizing that it's just a social club and none of the god stuff is real.
So in this scenario where you have a magical Genie, you would use a supernatural being to stop others from believing in supernatural beings?
Whoa dude. I just woke up and was not prepared for philosophy!
I’m trying to focus this answer on something that seems like a really small change:
I wish everyone is slightly more empathetic.
I feel like this could give us a lot of small nudges toward being better people and a better society. I wonder if a small nudge could end up having a profound effect.
Everyone is gifted with the ability to control their own fertility. You're only fertile if you want to be. The only chance for pregnancy to occur is if both partners want it to.
I imagine that would cause a severe population decline, and I'm fine with that. There's too many humans on this planet already.
Metacognition becomes routine for humans. We are able to better de-fuse from our thoughts, and recognize them not as reality but as thoughts about reality.
Not a very small thing maybe, but: All people gain ability to instantly recognise bullshit (at work, in media, interpersonal relationships, etc)
I get your intent... I think, but taken literally that's going to cause some issues. A virus that causes necrotic butt holes... Hmmm.
Technically that's just making the hole bigger. It'd have to seal them shut.
As an American, one of the most positive things that could happen to the world is the abolishment of the United States as a government. We're directly or indirectly responsible for most of the ethnic cleansing that has gone on the last several decades.
Every figure leading every cult of personality is now seen as an imposter pretending to be themselves. For example, people think some orange-faced lunatic keeps trying to get on stage at a Trump rally, but Trump himself just disappeared.
