Yes it's likely that I'm over-thinking this... It does not feel good enough since it would be ~opening new tabs and~ make me go through a lot more effort than necessary, and it feels like I would be overwhelmed and give up eventually.

There's no magic to learning. It takes some effort on your part.

To someone who doesn't actually know many of the terms here, it sounds like they didn't accomplish much. They defined a stronger form of locality called "bi-locality" and found a way to violate it. The structure of the argument is, "We stood up a strawman and knocked it down," which sounds pretty weak. Is bi-locality an inherently interesting property? Does all classical computation follow it? I don't know enough to…

Weaker than "I don't understand what the paper says, only read a high level layman summary, not sure even what what the experiment was for, but I'm gonna piss on it anyway"?

Even assuming what you already describe, the ability to show bi-locality as a new lower bound above which locality constraints apply, is very interesting, and nothing like a strawman.

It would only be a strawman if they claimed they violated locality in general.

Going meta here, speaking from the perspective of a software engineer with a great interest for physics. There are a lot of terms I do not fully understand in this article. Can you recommend an application that would allow me to select for example the words "distant particles can be correlated in ways that are impossible for classical objects" and find out what lead to that discovery? Or what does "Bell inequality" r…

>Can you recommend an application that would allow me to select for example the words "distant particles can be correlated in ways that are impossible for classical objects" and find out what lead to that discovery? Or what does "Bell inequality" really mean? If not, are there recommended methods of understanding articles better?

Venkman: Ray, pretend for a moment that I don't know anything about metallurgy, engineering, or physics, and just tell me what the hell is going on.

Stantz: You never studied.

(Ghostbusters)

Just studying the principles -- e.g. reading an entry level Physics/QM book, would be better and more solid than surfing around, or asking for opinions on forums (which you couldn't evaluate anyway -- tons of bogus opinions in any kind of forum), or googling stuff.

Stuff like "Bell's inequality" are so basic that merely surfing and skimming wouldn't help (it would be all a kind of concept soup in the end). You can do that with more advanced notions.

I was thinking a Chrome extension to automate this process would be a great way to turn "inaccessible science gibberish" into "Eli5" for a mass of people (I'd like to read that but I'm not willing to do any work other than install a Chrome xtension)

While you don't need new tabs to google a term with some addons, actual knowledge of the subject, even at a basic level, takes a lot more effort than opening tabs.

There's no magic bullet to learning.

Can you recommend an entry level Physics/QM book?

That isn't the structure of the argument at all. If you don't understand the terms, how did you manage to conclude it was a strawman?

They took an prediction of existing theory that violates a weaker form of locality (i.e. demonstrated stronger non-locality), and realized it experimentally. They also didn't invent bilocality in any case.
