Agreed. Even if it's impossible for someone to understand all of it, it's possible for scientists to understand parts of it, make models, and use those models to understand more, and improve them. After many iterations you'll get a full working model than can be used to invent better brains than ours. That we're so early in this cycle doesn't mean it's impossible.
