You didn't understand a single thing then. Endless didn't exist because others remembered them, but because of their own memories. Sphene couldn't let go of the actual people and used their memories to create them as AI.

And that was the whole point of letting go and YOU remembering others. As long as YOU remember them, they are not truly dead.
