Amara Graps could perhaps straighten me out, but I understood that star dust
will form a disk always, as opposed to a spherical dust cloud.

Again perhaps I misunderstood.  Is not an MBrain a subset of a Dyson swarm?
A particularly well organized and intentionally interconnected version, a
specialized unified and self-aware Dyson swarm?
