Isn't that a fundamental misunderstanding of the definition of "observer" in quantum physics? To "observe" is to cause a quantum system to interact in such a way that collapses probabilities. Whether there is a living observer is totally irrelevant.
if I remember correctly, this paper specifically tries to prove that those are the same
Only for non-physicists and physicists wondering about things outside of physics.
AFAIK the details are unknown (e.g. what constitutes the boundary between the “measuring” system and the one that’s being “measured”), but the “alive”-ness of the observer is definitely known to be irrelevant.
