We don't know that reality is deterministic and in fact right now
the overwhelming evidence very strongly suggests that it is not.
Everett restores determinacy in physics. The SWE's solutions are
deterministic.
I don't think that physical indeterminacy makes sense, nor that it is
something testable.

software, and such software can make an error with respect to the
goal (like "survive").
And the only things we have found that have goals are humans and
some of the higher animals, there is not a scrap of evidence that
anything else does including reality or the universe or the
multiverse if such a thing turns out to exist. Thus although humans
may like or dislike what the universe does (I personally dislike the
ban on faster than light travel because Star Wars was cool) from the
universe's point of view it can't do anything wrong, or anything
right for that matter.
Indeed. Same for arithmetical truth a priori, from which the
multiverse percolates in some sense.
