It was a Royal Institution public lecture,
"Will AI outsmart human intelligence? - with 'Godfather of AI' Geoffrey Hinton",
https://www.youtube.com/watch?v=IkdziSLYzHwUltimately I somehwat disagreed with some of Hintons points in this talk, and after some thought I came up with specific reasons/doubts, and yet at the same time, his intuitive explanations helped shift my views somewhat as well.
