Even though I fancy myself a bit of a writer, I wouldn't say that my grasp of the most basic aspects of writing and/or reading comprehension are my strong suits. Luckily, these are shortcomings which can be easily rectified with the aid of either computers or reading things over again. The more advanced aspects of literary skills are those which I have a much better grasp of. These are also skills which computers wouldn't help much in bolstering.
Or now anyway, I hear "Avatar II: Escape to Refugevania" being drafted completely via an A.I. Mad Libs.
