What part of GIGO do these clowns continue to refuse to understand?
In order to "predict" anything, the penomena and all their nuances must be fully understood. I continue to believe that, even in 2106, that will not be the case.
Just think for a second; of course that's not true. I've been watching ESPN Sportscenter just about everyday, and they're doing this thing called "The Ultimate NFL Depth Chart", and they're "predicting" who'll make the playoffs and win the Super Bowl. One major injury, and I'd throw that whole framework onto the trash heap. (Even without a major injury, football is unpredictable enough that there's no way it will play out as they "predicted". That doesn't stop them from making predictions, does it?)
What you may be trying to say is that the only way that a prediction will have 100% certainty, all of the influences must be understood perfectly. There's a name for that: Omniscient God. The rest of us are operating on incomplete knowledge, but that doesn't mean we can't make informed predictions.
