Conway's Life is computable but not predictable, there is no
shortcut so the only way to know what it will do is watch the
program run and see; however Conway's Life is not random either.
Life is computable because there is always something (the
previous generational life pattern) that if inputted into a computer
running the Life program will cause the computer to output the next
generation Life pattern. But a event is random if and only if it is
a event without a cause, so if something is computable it can not be
random. There is no law of logic that demands every event must have
a cause and in the 20th century some events in physics were
discovered that had no cause, in other words were random.
Only if you use the collapse assumption, which does not make much
sense. If not, as I said, it is a sepcial case of the comp FPI. That
is the interest of Everett: suppressing 3p indeterminacy, non-
locality, and collapse or other events without a cause (the mark of
irrationality ... for Einstein).
