This article does not take into account quantum phenomenon. It's possible that instead of being limited by the speed of light transmissions, such a system uses quantum phenomenon for communication. Which then would make the whole argument that this article makes invalid. It's based on the premise that life would be based on the same sort of physics as life on Earth... which does not make sense as such life if it exists would evolve using a different set of rules which would include things such as limits on speed of light transmission in such large systems... so it would've learned to exploit quantum phenomenon for transmission.

edit:

Superluminal, or faster than light, communication is said not to work because it allows information to be sent into the past. There is however non-locality which is not the same thing. Sorry not an expert on this, but this seems to apply to the exact discussion.

There are no quantum effects that allow superluminal communication of information.

It is not possible to use quantum phenomena for faster-than-light communication. It's fine to speculate about completely new physics allowing for such communication, but it really doesn't have to do much with what we call quantum physics.

We still don't know if the Universe itself isn't a living organism with us playing the role of tiny viruses that require intelligence/consciousness to fulfill certain tasks, like what gut bacteria does for us.

We do. If you bothered to read the article, it makes a point that the communication speed between the components would be slow enough (even at light speed signaling) that the age of the universe would not have permitted sufficient time for such an organism to evolve and do anything.

It doesn't need to take into account "quantum phenomenon" because the phenomenon you are citing is fictitious.

I'm no expert on xenobiology, but it seems like in our search for life we're always looking for life like Earth's. Are we even looking for life at much different scales of size or time?
