What would that mean? What would be real? Even in my thesis, electrons
are supposed to have some degree of reality like relative stability
as mind pattern in normal machine dreams (1-person plural histories)

With comp I will still be able to deduce the laws of physics ...
I could miss some intermediate level. This will depends of the story
through which you come to implement "me".

I guess no. That level of description is too high.

Not if I begin to suspect comp is true. I will stop to promote
anything as real physical entities, except those dream invariants
shared by all "physical" dreams.
(I recall that dream = computations "observed" from a 1-person (plural)
point of view).
Could you tell us what is considered real by Gerard 't Hooft?
