Actually I agree with you. I think "we" abandoned Harvard hardware like the Burroughs too soon and should consider more security in the hardware design that also doesn't rely on crypto. Ihe experience I have is the AVR micro processors which have the code blown into the NV flash. Of course, the first thing someone will write for it is LISP, thus invalidating your "old rules of code" by using "old code design". These days, one can run OS from an FPGA without impossible effort. If I had significant financials at stake, that's what I would be doing. I have had no losses, time or money, from viruses, worms, trojans or otherwise in my 25 years of computer use. I must be just lucky.
