Geoffrey Hinton's tech-talk in 2007 (!) at Google is a great watch (with a heavy dose of technical jargon [0] plus some dry British humour interlaced throughout). He explains digit recognition (vs SVM) [1], document classification (vs LSH), and breifly summarises image classification [2] problems and how they were solved: https://youtu.be/AyzOUbkUf3M
You could instantly see the results he presents were way better than what was state of the art at that time. Amazing.
