MIT AGI: OpenAI Meta-Learning and Self-Play (Ilya Sutskever)

I recently noticed this lecture series at MIT, focusing on AGI. This talk by Ilya Sutskever (OpenAI) is very good. There are several more in this series: playlist.

In Q&A Sutskever notes that it is not known whether/how human brains do backpropagation, which seems central to training of deep networks. Any neuroscientists out there want to take up this question?
