Stop playing the C P Snow game Mr Meyer. As a student of literature, you know better than to take metaphors literally. And both the Copenhagen interpretation* and the multiple worlds description are metaphorical attempts to describe what goes on in quantum interactions. As are others, the pilot-wave etc. What is certain is that there are lots of queer phenomena to talk about, and to get a handle on somehow, and that common-sense, Newtonian, physics can't do it. The purpose of metaphors is to inspire ways of exploring further, leading to experiments that support the metaphor, or disprove it (note: NOTHING in science can be proved, only falsified or not). For what it's worth (I can't play the quantum game because there's a glass ceiling on my maths), if you can base an industrial process on something, it's real. Let's see where quantum computing gets us.

On the other hand, I'm pretty sure all the real participants feel sure they are missing something important (that's what they are in science for, after all). A bit like astronomy pre- Copernicus: if it doesn't fit the data, add another epicycle. I wonder what science would have been like if the Fourier series had been discovered in the fifteenth century?

*that the state is indeterminate until observed:

There was a young man who said "God
Must find it exceedingly odd
To think that that tree
Should continue to be
When there's no one about in the quad.

Which elicited the response:

Dear Sir, Your astonishment's odd:
I am always about in the Quad.
And that's why the tree
Will continue to be,
Since observed by Yours faithfully, God.

Touche. However, if God observes everything and collapses all wave functions, there shouldn't be any quantum effects to explain.
