Whaaaaat?? Just a NAND gate? Nah, hardware is done on a combination of standard cell library, RAM, ROM&#x2F;flash, and analog components. You can&#x27;t even get the volatage right with just a NAND gate.<p>Far as symmetry, there&#x27;s potential there given some work is reducing it to math and simple constructs. Hardware too. Ill try to rrmember to give you a link when I&#x27;m off work.
