Fritz Griffith:

*>for every split in which we are favored to follow a certain world, there

*>exists another world of equally real people who assumed they would follow
*

*>the same path, who instead ended up in the so-called unlikely world.
*

*>Because the people in both worlds are equally real, there is no way
*

*>to say that we are more likely to follow either path; rather, between
*

*>this single-split example, the chance would be 50/50 as to which world
*

*>we would end up in. It would be arrogant to assume that we would have
*

*>to be the people in the more probable world. Considering all possible
*

*>worlds, we are back to the drawing board - the chance of us actually
*

*>being in a world that isn't chaotic is pretty much nonexistant.
*

*>Let me know if and why this doesn't make sense.

I am just repeating the same thing again (from the 97 paper): according to

UTM theory chance is not 50/50 because of the universal prior. There are

no real "splits" - there are just many different algorithms yielding

identical results for some time, then continuing with different outputs.

Given the universal prior, whenever there is a "split" the continuation

corresponding to the shorter algorithm is more likely. Roughly speaking,

probably the algorithm for your universe will compute the simplest future

split sequence compatible with past data.
