It’s a recording of a talk. Feel free to point out other sources but there doesn’t seem like much to object to here.

https://lpc.events/event/19/contributions/2099/ is a much better reference in my view. It is the original conference website, it contains all the material in text format as well, and it does not force you to watch a video (and maybe an ad or two before that, idk, I use adblock). I call this link "primary" and the Youtube video "secondary" (as well as Phoronix).
