"No. We don't need to invoke any special role for consciousness in order to address the quantum measurement problem. We've seen several counterexamples. Many-Worlds is an explicit example, accounting for the apparent collapse of the wave function using the purely mechanistic process of decoherence and branching. We're allowed to contemplate the possibility that consciousness is somehow involved, but it's just as certainly not forced on us by anything we currently understand. [...] We have very straightforward and compelling models of the world in which reality exists independently of us; there's no need to think we bring reality into existence by observing or thinking about it."
