where would this device get the data necessary to craft future generational visions?  It can't. That's really my whole point. The Columns Ter'angreal did something that all of our previous understanding of how it might work says it can't do. When there is and alternative explanation that doesn't require turning years of consensus on its ear, I prefer the alternative to trying to come up with a new explanation for how the ter'angreal works.  Yet we see it do something that appears illogical, or requiring modification of what seems to be simple programming.
