The problem is... the moment someone gets it and it really solves hard problems and solves scifi level shenanigans, the given country that owns it, could gain such unfathomable lead above anyone else that it will almost surely lead to an all out war. I don't even know whether it is possible to conceal that you have such capability....

Imagine all the fear- and warmongering kingmakers and powerful individuals when they realize they have no power over anything or anyone.....so game over for them. They won't like it at all, at all.

Another problem, that in order to make it understand real life, it needs robots or humans wired into it (brain interfaces) in order to test certain things in the real world. And that is another level we know almost nothing about, at least on the surface.

PS: do these self improving harnesses even work?
