Hmmm
I tend to agree with John Clark's pessimism, on ET, but basically, question his
axiomatic support (logically) of stuff like Von Neumann robots, and Dyson
spheres. It indeed has logic to it, yet it it too is pure imagination. We are
not sure, I am not sure, if the human species possesses Von Neumann capability,
we'd decide to tear apart the gas giants to make one quadrillion, 4-bedroom
ranch homes in the Earth-orbital suburb. (am American reference here, Dr.
Marchal).
What is far cheaper, energy-wise, is to doze in virtual realities, pretending
we a Captain Kirk, or Harriet Potter, or the Donald. I mean, both the Dyson
thing and Virch reality are a means to please the amygdala, if one is familiar
with basic, human, brain structure.
Secondly, nobody outside of what Dyson proposed years ago, and a few followers
looking at Tabby's Star, knows what such cosmic engineering really looks like?
What would your litmus test for space aliens, look like John, a galaxy of Blue
shift stars, or something that looks like concentric rings?

I don't think it's obvious that we could detect that a probe had been sent
to a star.
It would be obvious if it was a self replicating von Neumann probe, just one
probe could construct a Dyson Sphere around every star in the Galaxy in 50
million years, and that would be very hard to overlook.

And in any case the observable universe is very much bigger than our galaxy.
If ET existed the observable universe would look engineered, and it doesn't.
