Problem is that this can't possibly be 100% accurate. Not only do we have incomplete knowledge of our present, thus requiring us to make inevitably flawed assumptions, but there will be many different possible pasts that converge to any assumed present state, including pasts with different versions of the same people. In one timeline an executed criminal is really innocent but unjustly framed by the true perpetrator, in another he is guilty of the action but was coerced by secretive unseen parties into commiting the crime, and yet in another he is a guilty willing participant. Which was the "real" person? What was the "real" past?

Sounds like someone wants to play God using AI.
