Bibliographic Control Alphabet Soup: AACR to RDA and Evolution of MARC

I virtually attended this webinar using my phone and my laptop, in the comfort of my own home, with my dogs all present.  What a wonderful thing.
Initially I felt a little overwhelmed and my brain was telling me to sleep, but I perked up and became very absorbed after the first 10 minutes.  I took 7 pages of notes which I will turn into a paper of sorts, but I wanted to share some distillation with anyone who happens to stumble upon this blog.  Since they light-heartedly named the webinar an alphabet soup, I will keep with that theme.
One warning, though.
This whole THING is based on a "cloud computing" kind of principle.  There is a lot of stuff.  All stuff is attached to other stuff, and a lot of stuff is attached to other stuff, but not all stuff, and it can get really, really big and it can also get really, really small.
Unless you are familiar with clouds and this kind of world-ordering, nothing is going to make sense.  I'm sorry.  I struggled to get here. 
The further I went and the more detail-oriented I got, the more laden and spaghettied it seemed.  I realized just tonight that yes, while there are hundreds of layers to all this, I DON'T HAVE TO BE IN ALL OF THEM.
Essentially I am trying to get a good grasp on RDA and FRBR and how it/they are going to affect the cataloging of ephemera.  Better?  Worse?  Neither?  Completely Unrelated?
