Feynman doesn't disappoint. Although, I would have liked for him to make clear how quickly we (including physicists like him) get to "we have no idea". Sort of the overall arc of his answer made it seem that, well we know why but it would be impossible to explain it to you because it is incomparable to anything else you might know. But the reality is, we quickly arrive at the four fundamental forces (the we know of) for which we have no explanation, no further reducibility (that we know of). We know they exist because we can observe them or work them out mathematically. But we have to just accept them on their face as they are in order for the rest of the universe to make sense.
