Induction cookware isn’t just about making the food hot. You have to be able to do all the other things a chef does in a pan. Stirring, spooning sauce over food, and those operations were developed with a pan on a heat source. Nobody would buy a cooktop that required completely rethinking cooking, so they make a compromise that works with normal-ish pans.

An induction furnace is a narrow process, melting metal, and the closer the shape is to a sphere, the less heat loss.

Different problem, different solution.
