So let's look at the premises that underlie what you claim is a flawed conclusion. Basically:

3b. If 3, then once those interactions take place, another set of conditions is generated, and from that set of conditions, another infallible prediction can be made -- this can continue ad infinitum.
4. If all future interactions can (theoretically) be infallibly predicted, they are predestined. That is, what happens is the only thing that could have happened.
Now, again, I don't necessarily buy the whole argument, but I do think this is along the lines Harris is thinking. His explanation of it is a whole lot more developed than mine, but that's the gist of it.
I'm in favor of liberalized immigration because of the effect it would have on restaurants. I'd let everybody in except the English.
