I did suspect that "Garret then claims that this can be used for superluminal communication" missed that you were using this as a kind of reductio, but I then took it to mean that your reductio was not working how you expected it to. Probably I should re-watch the video - it's been a couple of years.
> your reductio was not working how you expected it to
Actually, it pretty much works exactly how I expected, and has for 25 years (I started down this road in 1990 when the EPRG paradox first occurred to me. It took me ten years to find someone who knew the answer.)
The problem is when people look at EPRG out of context and think that my thesis is that I've invented FTL and therefore I am the World's Greatest Physicist. (And now some moron is probably going to cite this very comment and say that I've claimed to be the Worlds Greatest Physicist because they saw that I wrote "... I am the World's Greatest Physicist" and they don't have time to read the part that they elided.)
The thing that people who critique my work generally miss is that it is not about physics, it's about pedagogy. It's about how the physics is explained. Everyone agrees on the physics. It's the explanation that is at issue. The whole first half of the talk is the problem statement.
(God damn this is annoying: "I'm afraid I won't have time to critique whatever it is he says in the second half of the video." Well, the second half is where I explain why the EPRG paradox doesn't actually work. By the time I gave that talk I already knew that people got this wrong, so I went to great lengths to highlight the fact that EPRG was a straw man. And then people jump into the middle of the video, see the story out of context, and say "This is wrong." Well, duh, of course it's wrong. That's the whole fucking point!)
