If the human brain was simple enough to be understood it would be too simple to understand. We will glean bits and pieces but a detailed functional understanding of an emergent system as large, containing as much feedback (within feedback), and with as enormous a connectivity as any large (or probably even small) mammalian brain is far beyond any reasonable expectation ever.
