  We critically discuss the possibility that the 125 GeV boson recently
discovered at the LHC is the holographic techni-dilaton, a composite state
emerging from a strongly-coupled model of electroweak symmetry breaking. This
composite state differs from the SM for three main reasons. Its decay constant
is in general larger than the electroweak scale, hence suppressing all the
couplings to standard model particles with respect to an elementary Higgs
boson, with the exception of the coupling to photons and gluons, which is
expected to be larger than the standard-model equivalent.
  We discuss three classes of questions. Is it possible to lower the decay
constant, by changing the geometry of the holographic model? Is it possible to
lower the overall scale of the strong dynamics, by modifying the way in which
electroweak symmetry breaking is implemented in the holographic model? Is there
a clear indication in the data that production mechanisms other than
gluon-gluon fusion have been observed, disfavoring models in which the
holographic techni-dilaton has a large decay constant?
  We show that all of these questions are still open, given the present status
of theoretical as well as phenomenological studies, and that at present the
techni-dilaton hypothesis yields a fit to the data which is either as good as
the elementary Higgs hypothesis, or marginally better, depending on what sets
of data are used in the fit. We identify clear strategies for future work aimed
at addressing these three classes of open questions.
  In the process, we also compute the complete scalar spectrum of the
two-scalar truncation describing the GPPZ model, as well as the decay constant
of the holographic techni-dilaton in this model.
