Wave function collapse is not tenable as part of quantum theory. The "decoherence" process holds ground currently as a quantum mechanical description of the measurement process and it doesn't make absurd distinctions like "observer versus observed". Less wrong has a layman's description of decoherence here - http://lesswrong.com/lw/pp/decoherence/ http://lesswrong.com/lw/pp/decoherence/
