possibility of an anthropic explanation of the Higgs puzzle

From his original paper :

<<<<<
In recent work, Weinberg has addressed the question of whether the Anthropic
Principle can explain the smallness of the cosmological constant [3].
Roughly stated, the Anthropic Principle [4] says that the parameters of the
universe that we observe are governed by the requirement that they must be
able to support intelligent life, as otherwise we would not exist to observe
our universe. If there is only one single “universe”, with the same laws and
parameters everywhere, this is far from a satisfactory physical explanation.
However, it has been realized that some physical theories can support the
existence of separated domains in the universe in which different parameters
and even different gauge groups are applicable. For example, in chaotic inflation
[5] different domains have different Higgs vacuum expectation values,
selecting different effective particle physics theories. Such domains could be
regarded as, effectively, different universes. This idea that multiple “universes”
can exist takes the Copernican revolution to the ultimate limit —
even our universe may not be unique. In a multiple universe theory, the
anthropic requirement that we live in a universe with viable parameters is as
natural as is the good fortune that we happen to live on a planet that has a
1
temperature ideal for life.

Discussions of the Anthropic Principle often end up dangerously close to
being non-scientific.

Has he actually FOUND intelligent life?
