This makes no sense in engineering terms.

What are you trying to maximize/minimise?

You would be trying to get as much computation out of an object as you
could while minimizing the distance between computational nodes.  You
also need to feed power in and radiate waste heat.

As far as uploading goes, I don't think it will become popular until
it is bidirectional.  And as far as humans merging, that's way too
much like death.

That many in that volume would still be diffuse (and possibly too diffuse to adequately explain the dimming.)  Imagine a trillion such earth-volume JBrains, so each node occupies an average volume of about a cubic kilometer.  They can maneuver as groups, even as they are themselves roughly bound together by slight gravitational attraction and held apart by slight net negative charge (which is easy to get a few AU from a star.)
