For a).1). you basically argued in favor of scalability. We don't know if we are on a training set more or less than a typical human at this point. If I would guess, I think high-bandwidth networked computers can be much more efficient at gathering training set than a single human. For a).2). you argued in favor of symbolic reasoning. My personal interpretation of that line of thinking is: it helps for us to understand complex thinking machines, but it is not necessarily the building block for the thinking machine. In the area of AI, there are a lot of opinions, but at the end of the day, builders win the argument. So far, what builders have shown gives me optimistic hope.
