PS. yes, yes, yes, there is irony in Dr. Kay's quote in that the Giza pyramids are of almost magical construction. He meant it metaphorically.
I think we should looking for the arch, and not be happy with piling rocks in a heap.
The Egyptian pyramids are quite incredible bits of engineering - hardly "rocks in a heap".
No I was nitpicking about some factual inaccuracies about Egyptian pyramids - I wasn't making any comment whatsoever about software.
