If Ebborians are classical entities, then exact copies are possible. An Ebborian can split and become two entities and accumulate two different sets of experiences. What if those two Ebborians then transfer memory files such that they now have identical experiences? (I appreciate this is not possible with biological entities because memories are not stored as discrete files).

You may be interested that I probed a similar question regarding how "qualia" come into play with this post about when two (classical) beings trade experiences.
