OK, I understand now. Yes, this is the quantum entanglement.
These folk don't speak from the heart. They either hide what they mean
or over-hype it, but what they are doing seems in the right
direction in a very general sense:

All this reminds me of Asimov's "I, Robot" and soon we will have
the "positronic" brain and robo-psychologists. This was my model
for such a brain and it's psychology:

Yes. I think it is just as do-able macroscopically as microscopically.
There is nothing about the microscopic domain that makes it the only
domain for "quantum" effects. "Quantum" is a very general idea.

I think that step will, and is, being skipped and people are
treating the subjectivity as a wave-theory and objectivity
as a particle-theory, and the next working hypothesis is
to do the same thing they did with space and time, and with
to wave and particle, to form quanta of these:
space-time
wave-particle
subjective-objective
mind-body
not to treat them separately, but integrally.

Definitely. The experimenter is a part of the observation at some
times to a large extent, and at other times to a lesser extent.
It depends on the "inner product" between the observer and the observed.
We can define that "inner product" in terms of the superposition
and/or entanglement of the local systems of the observed and the
observer. Have you already worked something like this out
mathematically ?
