Good stuff. I wish the slides went more into technical details of how each company solves these problems, but perhaps this is in the video? I haven't had the chance to watch it yet.
The talk was very funny, and I enjoyed it, but I did feel that it was a bit too much of a whirlwind tour to get as specific or concrete as I would prefer about the details of problems or their solutions. That would require like 3–4 hours though, far longer than the 40 minutes allotted. Or else would require cutting 3/4 of the topics covered to focus on a few.
Overall, I think it should be seen as a quick review. If you want the details you’ll have to dig into the many references.
