Chalk on a blackboard is physical too but it isn't entropy just because
you write S=kT ln(2).*

So you were wrong to write,``"measurement" implies that a
consciousness, or at least an intelligence, is involved'' or are
you now saying "measurement" has nothing to do with MW?
*Forget many worlds forget quantum mechanics, even Newton knew that if
you say "X measured my foot" then that implies X is consciousness, or
at least an intelligence. If you say "X changed my foot" then X may or
may not be conscious or intelligent.

Then what do you call all the decoherence implementing interactions not
involving consciousness or intelligence, which convert superpositions to
classical mixtures. It was my impression you called them all
measurements in the past.
