It's interesting that this problem does not exist in fusional languages. For instance, in Polish its even impossible (or really hard) to say:
MAN EATING PIRANHA MISTAKENLY SOLD AS PET FISH
in such ambiguous way. For instance:
"(MAN (EATING (PIRANHA))) MISTAKENLY SOLD AS PET FISH" = "człowiek jedzący piranię omyłkowo sprzedany jako ryba domowa"
((MAN-EATING) PIRANHA) MISTAKENLY SOLD AS PET FISH = "jedząca ludzi pirania omyłkowo sprzedana jako ryba domowa"
MAN EATING (PIRANHA (MISTAKENLY SOLD AS PET FISH)) = "człowiek jedzący piranię omyłkowo sprzedaną jako ryba domowa"
In your answer you introduced a new term, which wasn't present in parent's description of the situation: "reward". What if this superintelligent machine doesn't have any "reward"? If it really works exactly as described by the parent?
