Re: Conventional QTI = False

QTI, as formulated by some on this list (I call this conventional QTI), is
supposed to imply that you should experience becoming arbitrarily old with
probability one. It is this prediction that I am attacking.

I have no problems with the fact that according to quantum mechanics there
is a finite probability that bullets fired from a machine gun toward you
will all tunnel through your body. Or, that if you are thrown into a black
hole (Russell Standish's example), you might be emitted from the black hole
as Hawking radiation.

The mistake is that QTI ONLY considers certain branches were you survive
without memory loss, other branches are not considered. This leads to the
paradox that you should experience yourself being infinitely old etc..
