A Second Law After Moore

Moore's law is usually discussed as transistor density. The separate access question is what kinds of active devices can be built, tested, taught, and scaled outside the narrow path of conventional CMOS manufacturing.

The note points at an alternative switching-device idea: a device class intended to behave like a controllable switch without relying on the same semiconductor process assumptions as ordinary integrated circuits.

The important engineering questions are process window, switching speed, fanout, gain or restoration, leakage, repeatability, yield, interconnect, and how the device behaves when scaled from a large demonstrator toward a dense process.

Large versions matter because they can be inspected and taught. PCB-scale or printed demonstrators are not replacements for chips, but they can make the switching principle visible before photolithography enters the problem.

The tradeoff is clear: educational and maker-scale versions can reveal behavior, while useful computation still depends on density, repeatability, and a fabrication path that can produce many working devices.
