In using path integrals you arrive a probabilities for various

*Knowledge* is something having to do with human brains ("knowing"),
and when they became the "engines" of speaking and writing, then
*knowledge* could be communicated between intelligent beings. (Perhaps
other primates too are *knowledge*-able, but that's debatable.)
Now it seems to me that in the first few billion years at least of the
universe (after the Big Bang) there were no knowledge-able beings,
There hadn't been time for them to evolve anywhere.
But during that time quantum processes (and chemical, and at least
somewhere at some point biological precesses) were going along fine
without any knowledge-able beings exiting, and thus there was no
knowledge changing" -- because there was no knowledge during that time.
So how is knowledge needed as a concept in any way in QM when QM
processes were occurring in the universe fine before knowledge existed?
Whoever put "knowledge: in QM screwed up.
You're dodging the question like you're running for office on the
know-nothing ticket.
I've already asked all the way I can think of what it is that causes you
to change your estimate of the future evolution of a quantum system when
you measure it. I've concluded you have no knowledge of this process.
