SUMMARY

The forum discussion centers on the interpretations of Thomas Breuer's work regarding observers in quantum mechanics. Breuer's theories suggest that observers cannot predict their own behavior due to the indistinguishability of initial states, leading to implications about the nature of consciousness and free will. Participants express skepticism about the claims made by a forum user who posits that other humans are merely probabilistic Turing machines, contrasting this with the Many-Worlds Interpretation (MWI) that supports equal consciousness among observers. The consensus is that the original poster's conclusions are misinterpretations of Breuer's work, which does not support solipsism or the notion that other observers lack consciousness.

PREREQUISITES
  • Understanding of quantum mechanics principles, particularly observer effects.
  • Familiarity with Thomas Breuer's theories on subjective decoherence.
  • Knowledge of the Many-Worlds Interpretation (MWI) of quantum mechanics.
  • Basic comprehension of Gödel's incompleteness theorem and its implications.
NEXT STEPS
  • Read Thomas Breuer's papers on subjective decoherence and observer effects.
  • Explore the Many-Worlds Interpretation (MWI) and its implications for consciousness.
  • Investigate the relationship between quantum mechanics and Turing machines.
  • Study Gödel's incompleteness theorem and its relevance to quantum theories.
USEFUL FOR

This discussion is beneficial for physicists, philosophy of mind scholars, and anyone interested in the intersection of quantum mechanics and consciousness theories.

I didn't get the impression you were hinting at staclexchange stuff being right

Correct.

we can know, in principle, the observable properties of any particularly interesting thing, even of some piece of a human brain

Yes, if you only need to know particular observable properties that are compatible with each other.

all such properties together do specify the actual spacetime universe

You can't know all such properties together. You can only know a subset of them. That subset is not sufficient to specify an entire state for the universe.

I'm going to give Hartle's work a read.
Thanks for everything!

Honestly mate don't worry about it. That stackexchange stuff was nutty...
