One thing about the great setting of Eclipse Phase that make me thinking is why the TITANs uploaded millions of peoples during the Fall.
My theory is that they needed it to finish their singularity by acessing a potentiel fourth psi level where they need a vast number of ego to distrube the strain. Or something similar.
But my problem is if they needed other egos why not use forks of themselves (like the Fetches).
What are yours theorys ?
