Default Frank Wilczek's Emergent Gravity

On closer look Wilczek has a different idea than mine. His idea is
interesting.
I am claiming to derive Einstein's gravity with the cosmological term as
a large scale
limit of the exotic vacuum field from an instability at least in the QED
sector of
the micro-quantum vacuum. Wilczek in contrast never does any micro-quantum
theory that I can see in his paper? He already starts with "classical
fields" and
makes no attempt to derive gravity as emergent from the micro-quantum
standard
model.

I asked:
Is this where ODLRO MACRO-QUANTUM EMERGENCE is buried?

you get the Einstein-Hilbert Lagrangian.
All this is at conventional textbook level, for example,
section 14.6 of Unification and Supersymmetry, 2nd edition,
by Rabindra Mohapatra, Springer-Verlag 1992.
If you want a prominent establishment name dropped, Frank Wilczek
mentions the MacDowell-Mansouri mechanism in

Yes, thanks. This paper seems very relevant in accord with what I am
doing in a simpler way independently. Wilczek is one of the best
theoretical physicists around for sure. I heard him speak twice now
this year.

where he notes that the mechanism was also independently
formulated by Chamseddine and West.
The mechanism was invented to make it possible to get gravity
from the anti-deSitter part of Lie superalgebras used in
supergravity theories.
