I snip Robert's sound points abt mutation (directed at the url above) in
order to make one vehement point. By playfully/provocatively linking this
`directed mutation' argument (which I have not read in detail, only in
precis) to David Deutsch's version of Many Worlds, I was assuming a clear
distinction between quantum entanglement - and subsequent decoherence - in
*our* world, and the kind of thing Deutsch means when he speaks of `shadow
light' - mysterioso effects from adjacent not-quite-us superpositions. He
invokes these to account for the two slit interference fringes; I do not
think this discourse has anything directly to do with, say, the Aspect
entanglement experiments or anything similar.
I hope for clarification from the soi disant quantum mechanics on the list.
