“Real” truth is ultimately anchored to reality. You attach probabilities to datapoints based upon that reality anchoring, and include truthiness as another parameter.

For datapoints that are unsubstantiated or otherwise immeasurable, then it is excluded. I don’t need an LLM to comment on gossip or human-created issues. I need a machine that can assist in understanding and molding the universe, and helping elevate our kind. Elevation is a matter of understanding the truths of our universe and ourselves.

With good data, good extrapolations are more likely.
