*In a parallel computer there can be an unlimited number of NAND and
NOR gates that can perform their operations simultaneously, but you don't
have a parallel computer, or a computer of any sort, unless the output of
those NAND and NOR gates can communicate with each other. So if you want
your machine to run faster then you're going to have to place those gates
closer together, and you're going to need to decrease the wavelength of
light that you use for communication,  and the shorter the wavelength the
more energy it has, so if you keep going eventually you're going to produce
a Black Hole.*
