The most realistic scariest thing I believe in is the United States will be hit with a nuclear bomb. I hope this doesn't happen obviously, but unfortunately I do think we are going to get hit by one in our lifetime. I don't know which country or terrorist group would do it, but I feel it is the inevitable. There is no way these countries are spending billions of dollars and putting this much time and effort just for fun.

That humans with their ignorance, their religions, their beliefs, their intolerance, their profound sense of injustice, their love for abusing whatever power they have, their arrogance, their malevolence, that these humans could one day take over earth and be the dominant species that preys upon all other species including other humans

... Oh they already have, oops too late v_v

On a less important but still concerning issue:

That I never get perma-banned from VGC ... (?)

-I'll get a call saying something happened to my daughter.

-I also worry about another Holocaust... except this time it's for another race.

Extinction events:

The US will suffer another economic depression around 2030-2035. It will be caused by excessive amounts of debt: National debt,
student load debt, credit card debt, mortgage debt, etc...

The unemployment rate will reach a high of at least 25%. This depression will become a global one and last for several years.
