Answer: The observation does not require a conscious observer to have the collapse.

It depends in the interpretation of quantum mechanics. In some interpretations there is not even a collapse.

You might want to try David Lindley's layman-friendly book "Where does the weirdness go?". It won't quite answer your question, but it will explain more about how we think about wave function collapse these days.

You might also google for "quantum decoherence", but most of what you find will be less layman-friendly.
