# (Directed sex beats biological sex — the distinctly-AI superpower): on rugged landscapes, blind
# ("biological") sex suffers outbreeding depression (offspring worse than parents). But an AI can do
# what biology cannot: choose maximally-complementary mates, evaluate MANY recombinant offspring, and
# keep only the fittest, over several rounds (directed sex = iterated recombine-then-select, with no
# two-parent limit). Compare, across ruggedness K: best single parent vs RANDOM sex (blind) vs
# DIRECTED sex. Expect: random sex craters with ruggedness; directed sex avoids the catastrophe and
# matches or exceeds the best parent even when skills are entangled. Falsifier: directed sex does no
# better than random sex, or never recovers the best-parent level on rugged landscapes.
