Finally got around to watching (half), and she does explain it and gets into some real interesting technical stuff, so I judged too soon.

I think she's doing herself a disservice by opening with the dramatic reenactment though, because I bounced off on that, also on an earlier video. There's not really a gradual buildup either, so someone who actually likes the drama will get a cold blast of RAM spec sheet right after and likely stop there. Better to let everyone know what they're getting into at the start, right?
