The interesting part of QI is that the split happens at the moment of your death. So the state-machine-which-is-you continues being instantiated in at least one world. The idea of your consciousness surviving a quantum suicide doesn’t rely on it continuing in implementations of similar state machines, merely in the causal descendant of the state machine which you already inhabit.
It’s like your brain being duplicated, but those other copies are never woken up and are instantly killed. Only one copy is woken up. Which guarantees that prior to falling asleep, you can be confident you will wake up as that one specific copy.
There is no alternative to this, unless we require that personal identity requires something else than the continuity of pattern.
In big world immortality there are causally disconnected copies which survive in very remote regions of the universe. But if we don’t need continuity, but only similarity of minds, for identity, it is enough.

I don’t know about similarity… but I was just making a point that QI doesn’t require it.
