While I think many people find this definition of a zombie to be intuitive,
I would submit that a "zombie" in the sense that it is being used here is
not a valid class of intelligence unless you are willing to accept the
concept of magic computation.

The human mind does fuzzy lookups because it has insufficient memory
capacity to do non-fuzzy ones, but it really goes much further than
this. This type of fuzziness is *expected* for any vaguely optimal
small-memory predictor model in terms of generating "correct"
outputs. Given the same amount of memory as the human brain, the best
possible computer model for an AI would also exhibit a similar type of
fuzziness as an artifact of limited model memory. The human mind isn't
this way by coincidence; it represents nearly optimal computational
efficiency for the limited hardware it is built on (evolution in action),
both maximizing entropy and information quality on a memory starved system.
