Let me ask you this question: Where does the
'hardware' exist? How could the 'hardware' be
explained? The moment you have an explanation about
something which is understandable to a rational mind
the thing being 'explained' becomes indistinguishable
from 'software'.

But what explains the existence of 'physics' ?
Postulating the existence of 'hardware' at the bottom
always leaves something unexplained.

Either one is forced to conclude that certain aspects
of reality are simply unexplainable (which actually
leads to logical contradictions) or else one has to
dispense with the idea of 'hardware'.
