Part of it could be hardware related, we may need special chips just geared for this, with special coded sensors. Also, not everything we do is in our brain -- there's also muscle memory, and even tissue inside the gut stores some memories and 'knowledge'. Technically every cell in our body has some purpose/goal and can contribute to our entire being/feeling/mood/etc. There's a lot we don't know about conscience that makes developing an artificial one, very tough. That's why it's not estimated to happen till after 2050. I don't doubt it will happen, I don't doubt deep learning as is will be crucial to the discovery, I just think there's possibilities that undiscovered and better/alternate techniques might be discovered that could potentially trump dl as we now know it. There's a lot of things we do not know to get us to general ai, and to get there we may need to jump outside some 'boxes' that ai researches have put themselves into.
