Not parent but I think the link is pretty clear about what they want to say. I haven't got the time to actually watch the full video, but I could tell this is not a great presentation just by randomly clicking at random timestamps. And almost any presentation from Google (technical or not) I watched on YouTube is better than this. If you really want me to explain it for you, and just one issue: There are way too many words on your slides. P.S. You should click that link and go through it again. If you still don't get it, try once more.
