Medical research hasn't cracked step 1 either, at least not to a point of accurate simulation. Besides, if you could simulate a human brain, you will end up with something that needs to sleep, something with limited and unreliable memory, something that gets bored and distracted, something emotionally needy, etc. Then the extending of this chaotic, messy system is wildly unknown even if we could get a piece-for-piece replication to work. Such a thing would be of great benefit to medicine, but not really for AI to even start with until medicine is done reverse engineering it.
