IDK I’ve predicted my own birthday and Christmas correctly dozens of times.
I even predicted in the year 2000 that AI would become a thing around 2030, I admit that’s the most bulls eye long term prediction I’ve ever made. But still to make a blanket statement that it is unknowable is false.
There are trajectories, and there are statistics that can predict a lot.
Like for instance many of us predicted Russia would lose the war against Ukraine already a couple of months in.
And it was predict4ed 2 years ago that USA would go to war with Iran and lose.
I can also predict that the return of Jesus Christ will not happen within the next 2000 years either!
