Also, about the LEVAN thing... given the amount of data available online, both in various structured formats and unstructured formats, don't be surprised if deep learning will yield better and better results moving forward. To me though, they mostly seem evolutionary rather than revolutionary. I mean if you look back at the AI field, during the days before the "AI winter" came, huge amounts of data is one thing researchers back then didn't have available. This is not to say that there haven't been advances in learning algorithms at all recently. ..
