It’s not just that it implies faster-than-light communication, it’s that it implies communication at all.
Experiencing both bodies at the same time, you will be able to take actions in one body that you wouldn’t have done without the other one. It seems odd that with no biological changes to your brain, the mere existence of another similar brain changes how this one functions. Why would they be linked? This implies the observer is some external soul-like thing that can manipulate matter. If you can’t take actions based on your conscious experience, it implies the observer is dissociated from the brain and not created from it or able to interact with it.
I can definitely imagine a world where this is true, but it seems extremely unlikely based on what we currently know.
Yes, it would imply the observer is external, but then it also would not change anything about how the brain functions. (Or vice versa, but I prefer this one.) I am unconvinced of the truth of what you say in the last sentence of your second paragraph.
Either way, whether or not it might seem implausible, my question is why it is, or is not, implausible. Why exactly, based on what we currently know, is this extremely unlikely?
