Very different. Before copying there is one of you. What about

Obviously it does stop us since we disagree on the properties.

What we have here is a failure to communicate. I don't know how

to convey an idea you don't seem to understand. I hope I won't have to

keep trying. The idea is very very simple after all.

Suppose there are 1000 observers. For simplicity, assume each can

be labeled by a brain state which we can number from 1-1000, and that each

sees a different observation, which we can label by the observer number N.

Consider number 463. He sees an observation with various

characteristics, which we have labeled #463.. There is NOTHING random

about that, not in any way, shape or form, at all. Period. I can't

emphasize that enough.

Nor does he have any direct evidence to prove that the other

observers exist. But what he can do is guess that they exist based on

Occam's razor, thinking "the world would be simpler if I were one out of

1000 observers".

Suppose that each observer sees 10 coins. Our observer #463

notices that 9 out of the 10 are tails up, 1 is heads up. He guesses that

most observers see mostly tails up coins. In other words, he guesses that

the effective probability for each coin to be tails up is large.

To find out if this guess is correct we would "take a survey" of

all the observers. Still nothing random from any point of view.

Of course, the results of the survey are the same as if the coins

were randomly distributed with the appropriate probabilities. Hence the

term effective probability.

That's BS. They are plainly incompatible since they give

conflicting predictions. They are not just different levels of

description. And I see no reason why invoking QM would change anything.

On the contrary, we already know the physics, what we need for a

measurement theory are precisely things like the ASSA + computationalism.
