Actually, this is exactly what I do claim, so if you think I haven't
succeeded, I'd be very interested in learning why.

Note that the non-appearance of white rabbits comes from what I call
"robustness" of the observer, and robustness is not a general property
of Turing machines, which is why the white rabbit problem seems so
intractable in comp.

I argue why robustness should be a very likely property of observers
from evolutionary reasons, but perhaps the weakness of the argument is not yet
calculating the relative proportion of robust observers to non-robust
observers and relating this to the relative proportion of white
rabbits. I certainly believe it should more than compensate, but
perhaps I'm being overly optimistic.
