This is the full interview (about 30 minutes) with Ray in his Google office in Mountain View, CA, February 15, 2017. Ray gave generously of his time, and his replies to my questions were very focused, full of excellent content.
At the end of 2013, I made a documentary (https://youtu.be/5igUX43gkiU) about Ray, which includes clips from another interview. My goal was to provide a short video introduction to the life & thoughts of Ray, for those who know nothing about him and/or who want to know more. I hope you will check it out.
