Ed,
I am supposed to know marginally more than FA about QM, given a certain number of years dozing off in the back of lecture theatres... but what little I knew is largely forgotten and I certainly found that article heavy going (the few pages I could bear to read).
I'm not sure if the title 'Five big questions with pretty simple answers' was intended to be ironic or just a plot to make you feel very very small and unintelligent!
I certainly wouldn't ask E.Fredkin for a simple explanation of what those little loops are for on the Rab bag!
Though they might come in handy for stringing it up on a line to air?
