Because it doesn't exist anymore. Every human that has existed... not just that but all their interactions down to the smallest decisions etc..
This isn't a story you're telling where you reveal more of the plot as time goes by. Please explain yourself better. "It" is what? Why is every human that ever existed consequential?
Think about this:
I can walk to town via the country road, or I can walk to town via the suburban road. I get to the same place at the same time and everything that happens after is the same. There are two universes, one where i walked the country road, the other where i walked the suburban route. Those two existences have not converged, but they follow the exact same set of events until the death of the universe. The day after I walked to town, the AI was born. And it began simulating. Given it wants to kill the the humans who didnt support it, it doesnt care about the quantum changes of the wind on the suburban route, vs the country road.
Are you saying that the above is NOT possible? Why?
If you are not saying that, then why do you mandate that every single thing must be the same every time, when our only concern is that the AI assesses the loyalty of the people alive at the time it decided to judge mankind? (Remember thats the point of Roko's Basilisk).
If every permutation of existence is possible, then every single permutation must have some chance to reach our modern day world. Let's say the big bang false-started in another universe - it exploded, then imploded, then finally exploded again. It is now behind our universe in time. Now let's say a few factors in the formation of the milky way, sol, earth, and everything on it, allowed it to catch up to us perfectly. Is this not possible? Why not?
There are myriad permutations in the middle of those two extremes where we end up with unlimited identical earths all doing the same thing at the same time, but came to the modern existence in slightly different ways. Now the AI sims 30s in the future, and compares against the 30s that just happened.
edit:
You have no constructive argument to make other than "magic"/hand waving as a reason to overcome the obvious objections.
Everything in this thread we are discussing is because I brought it to the table.
