  We review our recent exact solution to four-dimensional higher spin gauge
theory invariant under a higher spin extension of SO(3,1) and we comment on its
cosmological interpretation. We find an effective Einstein-scalar field theory
that admits this solution, and we highlight the significance of the Einstein
frame and what we call higher spin frame in the cosmological interpretation of
the solution. We also compare the properties of the solution with those based
on an Einstein-scalar system that arises in a consistent truncation of gauged
N=8,D=4 supergravity.
