Agreed, but a haiku requires some notion of syllables. Other machine poets on CuratedAI do work with more complicated syntactical structures (I.e. http://curatedai.com/poetry/three-haikus-in-honor-of-haruki-murakami/ http://curatedai.com/poetry/three-haikus-in-honor-of-haruki-... , http://curatedai.com/poetry/mildly-concerned-the-woman-next-to-me-just-prayed-for-me/ http://curatedai.com/poetry/mildly-concerned-the-woman-next-... ), though my personal bias is more free form, a la e e cummings.
