No offense but that blog is a massive wall of text that is equal to asking someone to read a whole scientific paper (which is too much to ask for in the current context of discussion).
I came as far as dissecting the video about the DCs. It’s not much, maybe 1/10 of the total length.

It seems okayish written but I can’t add much else opinion to it as I havent read much further :/ I am sorry.
