> Schrödinger's point was that the conscious observer interpretation was absurd


This sounds right to me. And although poor ol' Heisenberg may have been much maligned for his trying to include such insignificant details of the universe as life and consciousness into a model of the world at least he had the gumption to try. The idea of completely consensual reality is no more absurd than this cat in the box.
Far more profound than any subjectivity, relativity or chaos theory are the ideas of the little-known German, Högel I'd say. He proved mathematically (some which way) that any expressions for a system created or perceived 'present' cannot be defined within its own terms or borders. This came coupled with the uncomfortable realization that 2+2 does not equal 4 but that it is merely a strong tendency.
