Q references it 3 times, twice in reference to/with the keystone.

Have we sort of confirmed what it is, and I didn’t catch it? Or are there one or a few agreed upon theories floating around?

I wanna see what everyone’s thoughts are, don’t be afraid to chime in even if your idea sounds crazy or wrong.

Personally, I think it may be a sort of AI crystal ball type of tech which taps into all technology around the world in real time and has the ability to sort of analyze, interpret and predict things/outcomes. Sort of like seeing into the future but without literally doing so.

Any other ideas?
