Interesting from my perspective as an educator. Even if an A.I. could learn, it would likely take much time to nurture the behaviors and learning that would make it similar to a human adult. I teach the 8th grade.
Daily, I see 8th graders who are immensely intelligent and capable of great things, but are also equally deficient in wisdom and experience, and therefore make terrifying choices. I see that any A.I. will have a very long series of learning experiences resembling those of a human being. 2029 for A.I. could be very much like people's expectations of being in flying cars at this point in time.
