If we believe that consciousness is the only ground of meaning and value (i.e. a universe without any conscious beings to experience it might as well not exist) then three conclusions may follow.
1) There would be nothing more worthwhile doing than enriching the conscious experience of self and others through activities like philosophy, meditation, the arts, counselling and cultivating our emotional lives, sciences, socialising and collaboration.
2) We might value neurologically diverse minds not only for their inherent worth as conscious beings but also perhaps as comparatively rare forms of consciousness.
3) Any meaning derived from the exploitation of conscious animals for food or sport would be at least partially undermined by violating this quality that makes all other value possible.
Finally, I’m not yet convinced about an AI singularity but (by these standards) bringing about a super-conscious intelligence may also be one of the most worthwhile things we could do. This providing it didn’t suffer inordinately or inflict greater net suffering on conscious life.
