The problem with Hans's approach is that with a low resolution image of
a highly detailed object like a chip it isn't all that hard to "see" small features
you're convinced are there even if they aren't. Or misinterpret the nature of,
or reason for, a minor physical design detail.

I am not saying Prescott doesn't have latent 64 bit capabilities of some kind
(I'd be surprised if it didn't). But Hans's evidence is less than compelling.
