No it's not. It provides an explanation of how the world can be
completely deterministic but to you as an observer within it
appear truly random, so that not even God would be able to tell
you what you will experience next.
That seems to me to be a very good case of something being "in-
principle unknowable". If it is not "in-principle unknowable", the
onus is on you to spell out the principles and circumstances in
which the time of the radioactive decay of a particular atom is
knowable in advance.
MWI means, "I know it when I see it." :-)
But more seriously, for FPI to apply to radioactive decay requires
a continuum of observers to observe the decay at all times.

That's what MWI advocates say. But that does not answer the basic
question -- there is nothing in that which will tell /me/ what time
or result /I/ will observe. That piece of information, which might
be of some importance to me, is always "in-principle unknowable".
Yes. And computationalism explains entirely why it has to be like
that, without invoking magic, nor even quantum physics. That piece of
information is not available to you, like in Helsinki, even God (like
Stathis remarked) cannot predict if you will find yourself in
Washington or in Moscow, and you know why in Helsinki. So there is
nothing more to be explained, as it is a consequence of
computationalism (the simplest theory of mind available today).
