No, it does because calculating all the consequences one's next action may be (and

Rational agents are entirely deterministic but that does NOT mean they're
predictable. It would only take you a few minutes to write a program to
look for the first even number greater than 2 that is not the sum of two
prime numbers and then stop. But will the machine your program is running
on ever stop before it runs out of memory X? Nobody knows. There is no
shortcut to knowing, there is no way to make a prediction, all you can do
is watch it and see what it does. And when the computer ends up doing
whatever it ends up doing the machine will be just as surprised at its
behavior as you are; it didn't know what it was going to do any better than
you did. If the computer stopped then afterward it figured it must have
chosen to stop, and if the computer didn't stop then it figured it chose to
ram the memory wall, but in either case it didn't know what it was going to
do until it did it, and neither did you.

If a rational agent can compute its utility to determine its next
course of action, then so can any observer with access to the same
Its got nothing to do with the Halting problem.
