<Snipped quote by Stabby>

The concern is that it might be inaccurate if our futures have diverged to the point that I disappear.

Any information is better then no information. Besides, you dissappearing is going to happen regardless, especially if we're working towards avoiding your future.
At that point it's either be left with faulty information that we can compare and contrast with, or be left with non and just hope that things work out.
