Dual Experience Ambiguity

Because many types of conscious experience are possible, there cannot be a single CF algorithm. As a minimum there is one core algorithm that can integrate multiple contents, as minor variations of the whole algorithm that generate a given experience. As such, it is conceivable that adding one extra algorithmic step at the end would create a new experience. Taken as a new whole, we've now got two moments of experience that are distinct but overlapping in their use of source material (since each requires the full preceding algorithm to qualify). How does the algorithm know which boundary to draw? If it draws both, which one is you?

This dual experience or dual self ambiguity is worse where we imagine it taking place in terms of the same terminal step of the CF algorithm, depending whether the boundary is drawn to include one additional midway input or one additional prior step. This situation is more bizarre, because both distinct 'moments of experience' now come into place at the same time, on the same substrate, following the same algorithmic step. If we deleted the previous steps having completed them, there is nothing in the present that tells you about their distinct nature, but nonetheless there are two separate simultaneous and overlapping experiences due to their overlapping but slightly distinct past lightcones.
