Basically it is a crystal ball which you can see into the future for POSSIBLE events.

I am not saying that 'magic' is not real.

But if the good guys had this machine, why didn't the bad guys who had it before use it to stop all eventualities for Trump being in office??

If Q and whitehats is saying that such machine exists then what they are doing is projecting. Projecting that they have control spreading fear among enemies.

Imagine deep state actors knowing this. Fear. Irrational decisions.

Imagine China knowing the US has this machine and can see the future of all battles. Fear.

With computers being super powerful now, is it just an illusion for a piece of AI software to predict all eventualities choosing a path instead of sonething that tells the future?
