A physical steampunk classifier is built from an aquarium air pump, gang valves and a Lego comparator that fuses 4-bit inputs into one output. It reliably separates linearly separable problems like even/odd and greater-than-3 by tuning valve weights, but prime detection requires extra layers and produces a false positive (1). The claim is that higher dimensions demand more layers and exponentially more training data, so with only 52 Mondays of operational logs models become fragile and easy for adversaries to break.
