(Disclaimer: physics undergrad.) I honestly wish we could get away from the word "observer" - it's more or less a historical accident and it probably confuses more than it helps. Talking about coherence and [decoherence](https://en.wikipedia.org/wiki/Quantum_decoherence https://en.wikipedia.org/wiki/Quantum_decoherence) is IMO a lot more intuitive. Always keep in mind, if you're reading about quantum physics and there's anything in there about consciousness or subjective experience or whatever, then you're either reading something very fringe, or you've misunderstood what the paper is saying. Quantum physics is weird, but it's not that weird.
