Quantum branching is “truly random” in the sense that branching the universe both ways is an irreducible source of new indexical ignorance. But the more important point is that unless the environment really is out to get you, you might be wiser to exploit the ways that you think the environment might depart from true randomness, rather than using a noise source to throw away this knowledge.
