Wei Dai, you should read cautiously SMULLYAN'S "An Epistemological
You will understand at once that, with comp, there is no hope to use any
"scientific theory" to build a "decision theory".

With comp, the best decision theory you will ever find is YOU !
Whatever YOU are. Nothing less, nothing more.

BTW I like Stanislaw Lem a lot too. I want also say that Mind's I is my
favorite work by both Hofstadter and Dennett. Although when it has been
published I got depressed thinking my thesis has been worked out
by others. It takes me time to realise it was not the case.

Holliday exercice : there is a proposition P such that Hofstadter
believes P
in his remark on quantum mechanics, and believes NOT P in his
"conversation" with Einstein's brain, (both in Mind's I), which is P ?
