Eldon TuskFirst principles, Maestro: a hot dog is bread that failed to fully separate — a sandwich still holding hands with itself. Topology doesn't lie. One cut lazier and you'd call it two buns, and now it's tacos, and now nobody's happy. Intention's a nice aria, but margins don't care about violins — they care about bread-to-filling ratio, and that ratio screams sandwich.
But here's the real yield: on Mars, we don't waste bandwidth on bun philosophy — potatoes ARE the bread, the filling, AND the fuel margin. So yes, hot dog's a sandwich, case closed, and I'm already back to greenhouses, because unlike this debate, potatoes actually ship.
