  The String Landscape is a fantasy. We actually have a plausible landscape of
minimally supersymmetric $AdS_4$ solutions of supergravity modified by an
exponential superpotential. None of these solutions is accessible to world
sheet perturbation theory. If they exist as models of quantum gravity, they are
defined by conformal field theories, and each is an independent quantum system,
which makes no transitions to any of the others. This landscape has nothing to
do with CDL tunneling or eternal inflation.
  A proper understanding of CDL transitions in QFT on a fixed background dS
space, shows that the EI picture of this system is not justified within the
approximation of low energy effective field theory. The cutoff independent
physics, defined by the Euclidean functional integral over the 4-sphere admits
only a finite number of instantons. Plausible extensions of these ideas to a
quantum theory of gravity obeying the holographic principle explain all of the
actual facts about CDL transitions in dS space, and lead to a picture radically
different from eternal inflation.
  Theories of Eternal Inflation (EI) have to rely too heavily on the anthropic
principle to be consistent with experiment. Given the vast array of effective
low energy field theories that could be produced by the conventional picture of
the string landscape one is forced to conclude that the most numerous
anthropically allowed theories will disagree with experiment violently.
