If humans even exist at that point, I would hope they would have the foresight to actually get off of Earth before it happens! And if that is the case then maybe end of war won’t happen either.
Humans have a very high opinion of themselves given that they have been on the Earth for such a short time in comparison to other species that have dominated it, and that isn’t even talking about how short the period of time they have been “waging war” is. A few million-year-old species talking about what will end war in billions of years from now. One that if it doesn’t destroy itself, is still subject to evolution and will even increase the speed of that becoming more and more of a cyborg. It is almost unconceivable that humans will be anything like we are today in a few billion years, if you can even call them humans at that time.
I remember when I was in Wisconsin, and the snow would pile up on the sides of the roads from snow plowing it. It would get higher and higher as winter went on. And the cars would drive by it and turn it all black. Not the most appealing landscape.
I’m sure, natural ignorance without a doubt. In fact, the greatest thing to worry about with artificial intelligence will be the fact that natural ignorance about exactly what artificial intelligence can and can’t do. For instance, expecting it to be unbiased when the whole point of “training” is to be biased in some ways. And another is people, believing that it is the same as human (or even superior) intelligence and believing the things is says/does without questioning if it is in fact correct.
Very good guess, I might have gone with the lip rings. :-)
