Watch this video. If you are anything like me, you have essentially zero understanding of what this guy is talking about. To start with. It very rapidly devolves into technical jargon and insider references to things that I don't really understand.
But you know what?
After awhile you probably kinda-sorta pick up on what is going on and can kinda-sorta understand what he's telling his audience. I think I am impressed at that part.
Watching this through also makes you realize that a computer-geek presentation really doesn't differ much from the talks we give in our science subfields. And if you skip through to the Q&A about two-thirds through, you'll see that this part is familiar too.
I think I may just make this a training video for my scientific trainees.
