I imagine it would have to be some sort of impractically large closed-loop steam system, probably running around the perimeter of the pot, with a rotating paddle inside. Not at all practical, but it would be neat.

Convention currents, but different soups will have different thicknesses and the more heat that’s required, but more likely it is the soup on the bottom will burn. Too many variables to design around.
You could make pots that can use a magnetic stirrer like they use in labs, but then you have to fish out a magnet from your soup.
