My pet theory is there is nothing to explain. It is emergent. Over the next couple of decades, hardware performance improvements and specializations plus algorithmic breakthroughs will make AI start to crawl up the chain from useful pattern matching from messy data to useful dullard able to reason. And we still won't know why because the "insight" is buried in the network state and our little human brains cannot deal with that level of detail.
