The only interesting aspect of yur fiction is its relation to reality,
and even that is only a matter of taste. Therefore this discussion has
mainly been about the relation of your annotations to the historical
and natural reality. Einstein's view is a part of historical reality
and therefore is relevant to the comparison.

The aspect of reality is actually important in physics, but reality is
not based on Einstein's views.

Reality is real, while the ideas and intentions of historical figures
are imaginary, because they are the fictions of a person.

That is more or less inevitable, because ideas are kind of thoughts,
which we humans breed out in our brains.

Such internal representations of the outer world are restricted to what
we have learned to model with our brain.

Since learning requires time and efforts, our ideas are usually only a
rough picture of what going on outside of our mind.

'History' has usually no relation to reality (internal, external, or
whatever) because history was written by Churchill.
