I don't. Rod logic takes about cm^3 to store relevant number of bits of
a human brain -- just to store, not to run it. In order to achieve that
10^6 speedup, you need a lot more.

(This relates for whole body emulation, native AI or transcoded folks
can be more compact, but just how more is not yet known).

That's a rather large assumption to make. Do not underestimate biology,
the more I study it, the more I'm impressed with its functionality
concentration. You need machine-phase to beat it, with self-assembly
you can only about match it.
