You can't recognize it directly, at least not with a 500-bit
subroutine. (Otherwise you could write a 510-bit program that iterates
through random substrings and picks the first sentient one, violating
the given World-Index-Compression postulate.) But in an ordered world,
you might "track down" a human (or other sentient being) within 500
bits with instructions like "keep searching in a straight line,
through an unbounded number of light-years, until you bump into
something that stands upright, uses grammar, and would get angry if I
punched it." (I'm making up these numbers, if I'm close to Realistic
Numbers it's just luck and not insight here.)
