So a small challenge Bill S. Using your new understanding describe the good and bad in this article
https://medium.com/starts-with-a-bang/embracing-your-fifth-dimension-2e02d9a0572cDo you think it successfully portraits an accurate representation of science?
My personal view is it basically comes across as an anti-string rant, which isn't really even relevant to many holographic theories. It then tries to put together a mumbo jumbo argument around what it refers to as a bulk spacetime which actually it doesn't ever define. I know what a spacetime bulk is in string theory but it doesn't make sense in this article which basically tries to avoid the stringy stuff.
The key point is it completely misses the fact in physics we are now forced to treat particles as excited states of an underlying physical field that is always already there. That is what makes it look holographic and is at complete odds to the classic physics where the field arise and expand out into space. Many people who don't believe in string theory accept and believe in a holographic scheme.
You said it yourself under QFT you are forced to see an electron or any "real" particle in classic physics as a sort of hologram of the field (Matrix like) ... it's not complicated and nothing to do with string theory or space bulk or the rest of the trash in the article.
Again it looks like another one of those situations that is an article by someone completely out of there depth. If I was being honest it looks like a case of google "holographic principle" and try and write an article using lots of catch phrases and google only picks up the story when the idea is formalized into string theory.
The article as written should have been called AdS/CFT correspondence and basically follows this story

http://www.thedailybeast.com/articles/2014/08/31/is-the-cosmos-just-a-big-hologram.htmlThe holographic principle isn’t a theory that describes our Universe yet: it’s more a fascinating conjecture that might let us solve some thorny problems in fundamental physics someday. However, a few researchers think we might be able to detect some discrepancies between the three dimensions of space we perceive and a lower-dimensional hologram in the structure of spacetime on the very microscopic level.
You will also find conflicting claims of who created the concept of holographic principle. The earliest reading I know of the claim is 1947 by Denis Gabor who actually invented Holography and want a guess what made him think of the idea
https://en.wikipedia.org/wiki/Dennis_GaborPerhaps I could suggest a reasonable read
https://books.google.com.au/books/about/...amp;redir_esc=yI graded the article D- as misdirected or misunderstanding.
