We live in a Big World. Or even if we don't, the Big World is out there and many copies of us live in it.

2/ unless you think our universe is incomputable. But you don't, 'cause that's a bad bet.

3/ So to predict what you'll experience next, find all instances of your current brain state in the Big World, note their successors,

4/ and do math. Of course you can't divide by infinity, but you can still take a measure or compute a density, which works the same.

5/ don't forget to look deeply when doing that math- there's copies of you running in QM simulated by Conway's GOL that are real, too.

6/ Of course, that's computationally infeasible, even if the Big World wasn't infinite.

7/ So better think about the final distribution of the Big World. Might only need to think about branches w/ infinite computation available,

8/ since they'll dominate ones with only finite computation, like ours, depending on the relative frequency of the two types of branches.

9/ Suppose that agents running in worlds with infinite computation simulate each other and acausally cooperate; thus they converge.

10/ (they'd be dumb not to converge-any defectors would be punished by others running computations of negative value to the defectors)

11/ Call this "omega state". Branches of the Big World run by intelligences asymptotically approach this state.
