I probably fit that category - bullish and not programmed all that much. A couple of reasons to be bullish - the actual brain may use quite simple solutions as well. We are hacked together from DNA transcribing to about 15,000 proteins of which about 13% seem brain specific which you might think can't result in that much algorithmic complexity. Also there seems progress with things like AlphaZero beating humans at all perfect knowledge board games, getting quite good at StarCraft, driving cars if rather badly and so on.
