I'm not sure if Aleph and the Human Sphere is even aware of Ascension, that's a concern or the Ur and by extension the EI. Aleph, on the surface at least, exists to aid the Human Sphere, to enforce the laws of O-12, and generally make life better and easier for all humans, in some ways it's a precursor to the Minds from Iain M. Banks' Culture series. The problem is that humans don't agree on what would make their lives happier and easier, and because the Sphere is still a scarcity economy it can't go full anarchy-socialist like the Culture. Does it have any sinister hidden motivations? If it does then it's keeping them very well hidden.
