As someone who has done a lot of those things (beyond programming), I can assuredly say that "writing about something" is neither a proof of understanding nor a proficiency in a subject. (Case in point, our educational system)

If indeed all the author's ideas are incomplete until written, his mistake is ascribing this to the power of his writing rather than the limits of his ideation.
