I kind of wanted people to respond to this bc it worries me a lot. I just don't dwell on this stuff as much or as deeply as I used to. I don't know if it's bc I've made up my mind about things, or my attention span has shrunk, or my brain can't cope anymore. None of those are good things.

I will add a quick addendum to admit that my doubts here may be a symptom of laziness. I've never studied this stuff formally: Dan & Amabel certainly understand it much better than me. It's possible there are angles & applications here I've not bothered to sniff out.
