I see this a lot, but I don't think it's accurate. It's definitely not possible for a brain to completely understand itself, as in know the state of every neuron and how all of those states will evolve over time, but that absolutely doesn't preclude a very complete understanding. The more we learn about the brain, the more it seems it is very friendly to a certain degree of abstraction. If it wasn't it wouldn't be able to turn sense data into world models so well!
