Oh I am happy to just enjoy and link to those

Doesn't have to be bad news! An abundance of explainers is only good for the world. Different explanations work for different people. Someday somebody will say "I read all the articles people recommended, and I don't know why but it only clicked for me when I read mcapodici's!"

I bet you just meant to share prior art and not be discouraging, Sam. But just saying :-)
