Perhaps I was not clear.

I suspect humans will abandon flesh (upload) within decades.  Maybe
not all of them, but the vast majority.

I think what we see at Tabby's Star (and 24 others in that cluster) is
orbiting "dyson patches" that provide the physical level substrate for
vast numbers (trillions?) of uploaded aliens and a simulated
environment. The biggest one of them (so far) is over 400 times the
area of the Earth, and even out at 7 AU it is collecting 1.4 million
times the energy humans use today.  Why so far out?  If these patches
are for computation, the low temperature (65 K) will reduce the error
rate (and the power needed for computation).

What limits the size?  Most likely the speed of light,  Bigger, and
communication would take an unreasonable (subjective) time to get from
edge to edge.

Now I could be dead wrong on this analysis, and I hope I am, we don't
need the competition.

But if I am not and we follow the aliens at Tabby's Star, things will
get very strange as we sail up the singularity curve.

PS.  Needless to say, full-scale nanotechnology is required to upload.
