Everyone is talking about Moore's law, but few know that there's a Second Law.

As a researcher in alternative chip technology, I invented a process that does not use semiconductors, nor it depends on ferromagnetic materials. A very simple switch design, surprisingly simple to explain. An equivalent to the ordinary vacuum tube, but it doesn't need vacuum, nor it has a positive work function to pull electrons out from the cathode (no heating, no special materials).

As a matter of fact, it can even be 3D printed via a 2-filament PLA printer, or made of ordinary PCB, so it's incredibly maker-friendly.

It does not require cryo to run, but can easily be pushed into terahertz range if you've got liquid nitrogen or a quantum lab.

Of course, you still will need photolythography, but the same switch will work being in the scale of millimeters, down to nanometers—so you can teach your EE students digital logic design on an enlarged version of your "chip."
