Maybe I'm mistaken, but I thought Einstein coined 'spooky action' sarcastically, to try and point out that it was absurd and violated his theories. I guess there aren't any better, sexy physicist names to put in the headline to attract clicks.

I think that's what happend. Schrodinger's cat was also initially conceived to ridicule the idea of quantum superposition.

The speed of light ought to be enough for anyone.

Except HFT traders. I'm sure somewhere some poor ops guy is being harangued with "Hey I hear the Chinese have this tech that is faster than light, I want that shit on my fiber right now dammit, I don't care if its alpha quality ok? What? No I don't need to know about physics, I pay you guys to know about physics, get me that tech now."

The name Big Bang was also coined to ridicule the idea.

"If it turns out that we actually can communicate data via quantum entanglement, we now know that it’ll be much faster than the speed of light." No, no, no, no, no. No. No. No. Quantum entanglement can not be used to communicate in that manner, on its own. This is well-established, and given the how mathematical the establishment is, it's not going to change anytime soon. No. No. No. Stop that. No.

There are skeptics who maintain that the various "no-signaling theorems" in physics are simply "begging the question" and rely on hypotheses that are too strong, e.g. http://people.uleth.ca/~kent.peacock/FQXi_v2.pdf

> One half of the pair was then observed, and the time for the other half to assume the same state is measured.

How??

How is it possible to observe whether or not an entangled particle has had its state resolved by the other particle being observed?

Well, actually it poses a lot of problems. Communications that have back-and-forth transfers can be very slow. For instance, if I wanted to do a distributed computation with a server on the other side of the world, it would be limited by the speed of light. From where I am to Australia is about 48 ms. So if I want to communicate there and receive a reply, that's about 1/10 of a second right there. I can only do that…

I believe the poster of this comment was being sarcastic, in the spirit of Bill Gates' [debatably misattributed] quote: "640K ought to be enough for anybody."

Yes, they shouldn't get their hopes up too much. Since the Many Worlds Interpretation is the simplest one, it is also the most likely one. With MWI there is no spooky action at a distance, and nothing is actually transmitted faster than the speed of light.
